To reproduce:
- Open gnomon on a non-map view, e.g. https://gnomon.space.nucleosynth.space/#timezone
- Switch to the map view
The map overlay bubbles will be in the wrong positions, at a narrower width than usual, and the text within them will be not centered properly!

Also, changing zoom level while in this state produces hilarious results.
Letting a clock tick happen while you have the map view open seems to fix this...
