Template editor crashes on Firefox

The drag & drop email editor crashes when I try to add an image block in Firefox 130. Works fine in Chrome.

Console error:

TypeError: Cannot read properties of undefined (reading 'getBoundingClientRect')

Happening on both Windows and macOS Firefox.

Thanks for the detailed report. This is a known Firefox issue with our drag-and-drop library. The getBoundingClientRect call fails on certain DOM elements in Firefox's rendering engine.

Workaround: use Chrome or Edge for now.

Fix will be in v4.7.1 — we're switching to a different drag library (SortableJS) that handles Firefox better.

Using Chrome as workaround. Looking forward to the fix!

v4.7.1 fixed it — Firefox works perfectly now with the new drag library.
