Subject: [PATCH] Remove Activity if it enters PiP without window
|
|
|
|
This is to prevent malicious app entering PiP without being visible
|
|
first, like blocking onResume from completion. Which in turn
|
|
leaves the PiP window in limbo and non-interactable.
|
|
|
|
Bug: 265293293
|
|
Test: atest PinnedStackTests
|
|
