Possible gnome-shell crash when making PiP window full screen

[yrro]

I got a crash when clicking the button within the PiP window that makes it full screen. This has only happened once, feel free to close if there's not enough info here to track the cause down.

Here are the log messages:

It occurs to me that this might not even be the fault of this extension. I filed it here because I've not seen the crash until I installed the extension, but again if you don't think it's the extension's fault feel free to close :)

[yrro]

I re-installed the extension recently and just got another crash with the same log messages from GNOME Shell. I had a YouTube video on top. I don't think I was interacting with the window myself. I think the crash happened when the video ended.

I still don't have much direct evidence tying the crash to this extension, but I don't remember having the same crash while the extension was uninstalled.
