...it tells us that there is 1 unknown edge, and 2 known edges.
...we need to figure out what the unknown reference is from, as that is where our leak really is.
...the goal is to eventually shrink down the “something else” category until there are only as many things in it as there are unknown references to the leaking object, and then you have your leaker.

Using media queries - CSS: Cascading Style Sheets
queries involving unknown media types are always false.

Syntax - CSS: Cascading Style Sheets
this leads to an important consequence: if one single basic selector is invalid, like when using an unknown pseudo-element or pseudo-class, the whole selector is invalid and therefore the entire rule is ignored (as invalid too).

<color> - CSS: Cascading Style Sheets
unlike html, css will completely ignore unknown keywords.

Using HTML sections and outlines - Developer guides
unknown elements are styled as display: inline by default, so you'll want to set them to display: block: article, aside, footer, header, nav, section { display: block; } of course the web developer can style them differently, but keep in mind that in a non-html5 browser, the default styling is different from what is expected for such elements.

note however that serving your pages as application/xhtml+xml will cause internet explorer 8 to show a download dialog box for an unknown format instead of displaying your page, as the first version of internet explorer with support for xhtml is internet explorer 9.

Common MIME types - HTTP
an unknown file type should use this type.

Reason: invalid token ‘xyz’ in CORS header ‘Access-Control-Allow-Headers’ - HTTP
this is a problem that most likely can only be fixed on the server side, by modifying the server's configuration to no longer send the invalid or unknown header name with the access-control-allow-headers header.

Reason: invalid token ‘xyz’ in CORS header ‘Access-Control-Allow-Methods’ - HTTP
this is a problem that most likely can only be fixed on the server side, by modifying the server's configuration to no longer send the invalid or unknown method name with the access-control-allow-methods header.

Content-Range - HTTP
<size> the total size of the document (or '*' if unknown).

Feature-Policy: unsized-media - HTTP
the page will re-flow every time an image with unknown dimensions is loaded.

Forwarded - HTTP
this can be either: an ip address (v4 or v6, optionally with a port, and ipv6 quoted and enclosed in square brackets), an obfuscated identifier (such as "_hidden" or "_secret"), or "unknown" when the preceding entity is not known (and you still want to indicate that forwarding of the request was made).

Warning - HTTP
<warn-agent> the name or pseudonym of the server or software adding the warning header (might be "-" when the agent is unknown).

HTTP Messages - HTTP
single-resource bodies, consisting of a single file of unknown length, encoded by chunks with transfer-encoding set to chunked.

HTTP Public Key Pinning (HPKP) - HTTP
if the server delivers an unknown public key, the client should present a warning to the user.

Keyed collections - JavaScript
(this can be bypassed using map = object.create(null).) these three tips can help you to decide whether to use a map or an object: use maps over objects when keys are unknown until run time, and when all keys are the same type and all values are the same type.

Object.getOwnPropertyDescriptors() - JavaScript
examples creating a shallow clone whereas the object.assign() method will only copy enumerable and own properties from a source object to a target object, you are able to use this method and object.create() for a shallow copy between two unknown objects: object.create( object.getprototypeof(obj), object.getownpropertydescriptors(obj) ); creating a subclass a typical way of creating a subclass is to define the subclass, set its prototype to an instance of the superclass, and then define properties on that instance.

String.prototype.charCodeAt() - JavaScript
'abc'.charcodeat(0) // returns 65 fixing charcodeat() to handle non-basic-multilingual-plane characters if their presence earlier in the string is unknown this version might be used in for loops and the like when it is unknown whether non-bmp characters exist before the specified index position.

Strict mode - JavaScript
strict mode makes with a syntax error, so there's no chance for a name in a with to refer to an unknown location at runtime: 'use strict'; var x = 17; with (obj) { // !!!
