Bug 253366 – Remove 'which' from 'KeyboardEvent.idl'

• Component: UI Events
• Status: RESOLVED FIXED

[Ahmad Saleem]

Hi Team,

We have this following FIXME: https://searchfox.org/wubkat/source/Source/WebCore/dom/UIEvent.idl#35

and Blink removed it as part of this commit - https://chromium.googlesource.com/chromium/src.git/+/cf13270c47f29b21ce7a8c937f598989cd66c840

Intent Thread of Blink - https://groups.google.com/a/chromium.org/g/blink-dev/c/6V4iHkqZXvQ

Just wanted to raise, so we can track the removal of this non-spec as well.

Thanks!

In this context, I read that Blink removed `which` from **KeyboardEvent and MouseEvent** but not from **UIEvent**.

The spec also keep it as legacy interface
https://w3c.github.io/uievents/#legacy-interface-UIEvent

Hence, I think we can remove the FIXME but not remove `UIEvent.which` even if we sort our interface to Blink.
This bug title should be changed.
