Render animation thumbnail sometimes uses incorrect palette

[nashalexander]

Environment

MacOS Firefox 108.0.2 (64-bit)

Replicate issue

1. Have two rooms and two palettes, room 0 has palette 0, room 1 palette 1
2. Switch the room editor to room 1
3. Playtest the game, which will begin play testing with room 0
4. Stop play testing. The room editor will switch back to room 1, however the graphical issue below will occur.

Description

I noticed at some point when editing a game, the animation thumbnails began using the incorrect palette colors and the incorrect values from that palette.

This screenshot displays the room's selected palette in the palette tool.

This screenshot displays the other palette I have, which is not the room's selected palette. Notice how the preview is using the incorrect colors from that palette as well for the background and sprite colors.

Temporary Fix

Switching from one room and back to the other fixes the issue. So I'm assuming there was some issue that created a mismatch between the stored room id and the actual room tool's id.

doesn't repro anymore - I think changes I made to how the renderer caching works may have fixed this one
