stopFollowingRaw method
void
stopFollowingRaw()
End the post-Try-now live window NOW (idempotent). Called when the sync sheet CLOSES (audit D): the window's whole rationale is "the user is watching their own tap play out", and once the sheet is dismissed nobody is — letting the window run on would spill up to 4s of raw flap onto the badge's now-unblocked liveRegion (a full stall label re-read per blip) and the send screen's pinned queue affordance. Closing it cannot re-create the dead tap the window fixes: the dwell resumes only once the watched surface is gone.
Implementation
void stopFollowingRaw() {
if (_disposed) return;
_stopFollow();
}
