Bug 131908 – [Mac] Unable to select 'Off' or 'Auto' from track menu when tracks consist of unsupported track types

• Component: Media
• Status: RESOLVED FIXED

[Brent Fulgham]

When Webkit is asked to display a media track menu with out-of-band tracks of an unsupported track type (e.g., TTML), you are not able to select the 'Off' menu item.

There is no user-visible impact here (since the track doesn't display whether it is selected or not), but it's unexpected behavior to select the 'Off' menu element, but for the menu to not show an 'Off' checked state.

I'm not sure if this would be better to just incorporate into the loop above?

prepare-ChangeLog doesn't like something about HTMLMediaElement.cpp so it thinks all changes are in parseAttribute, so you should fix this entry manually.

It could be, but I think it is probably easier to follow the logic this way.

trackToSelect is TextTrack::captionMenuOffItem so it can't be NULL, and TextTrack::captionMenuOffItem won't be in textTracks(), so this check can be removed.
