Panic in Reaper on Linux when closing plugin window

[ilmai]

Tested on two systems. I get this crash inside baseview when closing the plugin window of my plugin using Vizia:

[PolyVector]

I'm getting reports of the same issue from users, and can confirm it happens when using Vizia, Iced, and Egui, so it's not tied to Vizia specifically.

Edit: I should mention I reproduced the error using the nih-plug example plugins, and a Linux Mint (Debian Edition) VM. I've also seen it on regular Debian/Ubuntu VMs, but it was particularly quick to reproduce on the Mint (Debian Edition) one.
