Yes, I'm expected LockScreen well, as your comment. I've another patch for the similar issue at Bug 1081132, but it's now a demo patch and waiting Alive's opinion.

There are actually two issues in this bug. To reproduce this bug needs two preconditions:

1. App calls "mozLockOrientation" whenever the "resize" event is triggered.
2. App plays media by html5 video/audio tag even in background state.

An app which meets condition 1 causes lockscreen to become landscape (issue 1). Note that issue 1 can be recovered after you turn the screen off and turn it on again. An app meeting all conditions will cause the same symptom but cannot be recovered (issue 2).

Per comment 5, there is much chance that the patch of bug 1081132 can fix the issue 1 as well but we still need bug 1015073 to address the issue 2.

I recommand that we need to distinguish these two situations before dealing with this bug.
