Reviewed by Jer Noble.
MediaSourcePrivate::waitForTarget() sets m_reenqueuePending = true.
It was normally cleared by reenqueueMediaForTime(). However, when
prepareToSeek()
returned a non-indefinite time (meaning the synchronizer was already at the
target position),
continueSeek() took a fast path that called completeSeek() directly, skipping
reenqueueMediaForTime() entirely.
This left m_reenqueuePending stuck as true. Since
SourceBufferPrivate::provideMediaData()
bailed early when isReenqueuePending() was true, no new samples ever reached the
renderer after that point.
