Bugzilla

**Note**
* When the user plays a video (youtube/vimeo) and then stresses the URLbar entry/exit point for PiP, he will notice that the video stream might fail.

**Found in**
* Nightly v114.0a1

**Affected versions**
* Nightly v114.0a1
* Beta v113.0b7 (if the feature is enabled from config)

**Tested platforms**
* Affected platforms: Windows 10
* Unaffected platforms: to be investigated

**Steps to reproduce**
1. Play a youtube/vimeo video.
2. Stress-click the PiP URLbar entry/exit point.

**Expected result**
* The PiP is opened and closed successfully.

**Actual result**
* The video fails intermittently, causing the sound to play, but the video to turn black.
* This issue can be worked around if the video is paused and replayed from either the main player or the PiP OR by closing and re-opening the PiP.
* In some even lower reproduction rate, the PiP might be opened twice.

**Regression range**
* This is not a regression considering that this feature is still in the implementation phase.

**Note**
* When the user plays a video (youtube/vimeo) and then stresses the URLbar entry/exit point for PiP, he will notice that two PiP windows would be opened incorrectly or the video stream might fail.

**Found in**
* Nightly v114.0a1

**Affected versions**
* Nightly v114.0a1
* Beta v113.0b7 (if the feature is enabled from config)

**Tested platforms**
* Affected platforms: Windows 7, Windows 10, Windows 11
* Unaffected platforms: to be investigated

**Steps to reproduce**
1. Play a youtube/vimeo video.
2. Launch the PiP.
3. Click the URL bar entry point 3 times, quite fast.

**Expected result**
* No unexpected behaviors are observed.

**Actual result**
* Two PiP windows from the same source are being opened; one plays and the other is frozen. THis issue can be worked around by closing both the PiP's and opening another one.
* The video fails intermittently, causing the sound to play, but the video to turn black. This issue can be worked around if the video is paused and replayed from either the main player or the PiP OR by closing and re-opening the PiP.

**Regression range**
* This is not a regression considering that this feature is still in the implementation phase.

**Additional notes:**
* This issue might be occurring on lower-end systems or on specific ones.
