[Blocking Requested - why for this release]:

Bad user experience.
Suggest to fix on master branch, and then decide to see if we need to uplift patch.

Comment 7

[Jim Porter (:squib)]

I can't reproduce this anymore, but there is still some odd behavior in the scrubber.

Comment 10

[Jim Porter (:squib)]

Currently, what's happening is that we're not getting the "touchend" event once you slide on the utility tray, and so the scrubber thinks that the user is still pressing it. Pressing the scrubber again resolves it. This might be a system app bug, if the system app is swallowing events that we need to listen to. We should investigate why this is happening.

per irc conversation, leaving an NI to do initial investigation. you can do this after the search feature on music lands. 

thanks

This problem can be reproduced on latest build of Flame KK 2.5 with old Music app and NGA Music app.

Device information: 
Flame KK 2.5 Build ID: 20150922150204

Comment 13

[Jim Porter (:squib)]

Since this is happening with two completely-independent apps (music OGA and NGA), it's looking like this is a system app bug. I also don't see anything obvious in the music apps that would be causing this.

Comment 14

[Gregor Wagner [:gwagner]]

This doesn't seem to be a regression and we shipped 2.1 and 2.2 with it so it shouldn't block according to our criteria.

Comment 15

[Verson Xiong (Leave from Mozilla)]

This bug can't be reproduced on latest build of Aries KK v2.5/master Flame kk v2.5/master by the STR in comment 0, so I close this bug. If anyone can repro it, please reopen again.

Actual result:Seek bar will resume and progress bar works normally.
