This picks up stuff we didn't show in the viewer at all so far :/

Firefox windows:

This is also there on main, but there it's not shown as a toast notification

Edit: this is likely related to emil's comment here #8465 (comment)

it also needs a scroll bar 🤔 Can't reach the clear all anymore

(I provoked the error a bunch of time here, just as an example)

Quick UX feedback: I would expect the panel to close when I click outside of it.

All of the following scenarios now work as expected:

• Click toggle button: Panel is open
• Click toggle button twice: Panel is closed
• Click toggle button, click inside the panel: Panel is open
• Click toggle button, click outside of panel: Panel is closed
• Click toggle button, press escape: Panel is closed
• Select something in the selection/time panel, click toggle button, press escape: Panel is closed, selection is preserved

The layout for individual notifications is still pretty gnarly, but it doesn't seem like I'll be able to use egui_flex for that, as it doesn't support max-width combined with flex-grow

...or maybe I just flip the layout a bit and it will be good enough?
