Bugzilla

**Note**
* According to the [Nimbus Experiment Brief for PiP](https://docs.google.com/document/d/1Bxe_a3tk76MHdGCxMtfJ5KVLMDlNoX0QktiItKBm1ak/edit), when the user "interacts with the video" in a fresh profile, a Telemetry event pictureinpicture.saw_toggle with an attribute firstTime should be recorded, however, this event will only be displayed in the about:telemetry after the user CLICKS on the PiP button/toggle.

**Affected versions**
* Nightly v99.0a1

**Affected platforms**
* all

**Steps to reproduce**
1. Launch browser with a new profile. (media.videocontrols.picture-in-picture.video-toggle.has-used = false)
2. Open any video (https://www.youtube.com/watch?v=kaUemcqIQ-k)
3. Interact with the video (play/pause/hover the PiP button/toggle); Make sure that the PiP button/toggle gets displayed.
4. Go to about:telemetry and search events for "pictureinpicture"
Observe: A scalar named "pictureinpicture#saw_toggle#toggle" gets incremented at every appearance of the PiP button/toggle (when hovering a video).

**Expected result**
* An event should be displayed like:
122650 	pictureinpicture 	saw_toggle 	toggle 	null 	{"firstTime": "true"} 

**Actual result**
* No PiP events are being displayed on the Telemetry page.

5. Go back to the Youtube video tab and click the PiP toggle.
6. Go to about:telemetry and search events for "pictureinpicture"
Observe: Only now, an event is being shown like:
122650 	pictureinpicture 	saw_toggle 	toggle 	null 	{"firstTime": "true"} 

**Regression range**
* Not a recent regression.

**Additional notes**
* It appears that it is expected to record the "pictureinpicture saw_toggle" event the second it gets displayed, when in fact, it only gets recorded after clicking the PiP button/toggle. It is yet unknown if this behavior is correct or acceptable.
* Feel free to close the issue if invalid.
