[Fixed] computedStyleMap not supported in Firefox

Editing with the Designer in Firefox 121 stopped working for me within the last hour (2024-01-18 16:18GMT). I can select containers in the Designer, but any attempt to place a new component fails. The designer content panel is effectively frozen any time a component in the toolbox is selected for placement.

Looking at the Console, there is a fairly obvious culprit:

TypeError: e.computedStyleMap is not a function
E edit-state.ts:311
a edit-state.ts:342
A edit-state.ts:358
S designer2.bundle.js:20

A quick google suggests that computedStyleMap is not supported in Firefox, so either a) it was experimentally supported and a Firefox update I saw a notification about earlier has removed it; b) there has been an Anvil software update pushed this afternoon that has broken it in Firefox; or c) ???

I have no problems using the designer in Chrome.

Anyone know what the root cause might be?

Thanks for spotting this - a fix is on its way!

Update: This is now fixed!
