Some WebIDL operations / attributes incorrectly use _current_ realm instead of _relevant_
4+
https://bugs.webkit.org/show_bug.cgi?id=230941
5+
6+
Reviewed by Sam Weinig.
7+
8+
This patch replaces _current_ global object with _relevant_, as per recommendation
9+
for spec authors [1], for select WebIDL operations / attributes that satisfy all
10+
the following conditions:
11+
12+
1) it's an instance member: static ones and constructors can't use _relevant_;
13+
2) it's on standards track (not deprecated / WebKit-only / internal);
14+
3) the change is directly observable: global object is used for something
15+
beyond lifecycle / event loop / parsing CSS etc;
16+
4) the change either aligns WebKit with both Blink and Gecko,
17+
or the spec explicitly requires _relevant_ realm / settings object.
18+
19+
Most of the remaining [CallWith=GlobalObject] instances are correctly used for
20+
converting JS arguments to WebIDL values; the rest, along with _current_ Document
21+
and ScriptExecutionContext, either match the spec or replacing them with _relevant_
22+
global object is not directly observable (see condition #3).
23+
24+
This change is aimed at fixing web-exposed APIs rather than performing a global cleanup.
