718420 - Firefox don't remove id/name mappings from document object when the id has been removed

Status: RESOLVED DUPLICATE of bug 855971

(Core :: DOM: Core & HTML, defect)

Description

[Masatoshi Kimura [:emk]]

Attachment: Test

Steps to reproduce:
1. Open the attached test case.

Actual result:
Firefox: 42 [object HTMLImageElement] [object HTMLImageElement] 
Chrome/IE9: 42 42 42
Opera: 42 [object HTMLImageElement] 42

Expected result:
I believe Opera is right here per the current spec (correct me if I'm wrong).

This is basically the same as bug 307415.  New DOM bindings might fix this...

Comment 2

Attachment: Another test

Firefox: 42 [object HTMLImageElement] [object HTMLImageElement]
IE8: 42 42 42
Chrome: 42 undefined undefined
Opera: 42 42 42

What is the right behavior in this case? If I understand correctly, "42 [object HTMLImageElement] 42" is right because supported property names with [OverrideBuiltin] will have a priority to own properties (again, correct me if I'm wrong).
