Case maps fail to render on Firefox and fail to show case data on Chromium

[kortschak]

The district maps for both national and state wide data no longer render on firefox (90.0.2).

The situation is marginally better on chromium; the map renders, but not with any data.

@mcyph do you have time for this?

This appears to be fixed now (checked on FF and chromium).

This is broken again. Broken on both FF and chromium.
