"Customize" Email design button unresponsive

[stromfeldt]

Issue Summary

Nothing happens when clicking on the Customize button associated with the "Email design" feature (although the "Customize" text colour does change from grey to white on hover). The button used to work in a previous version, but as of version 3.39.0 (and possibly earlier) it no longer does anything. The issue persists across browsers. To make things confusing, I have another instance that is also on 3.39.0 where the button and functionality work just fine.

I'm sure there's many variables that could be at play, the only one popping into my head being that the version that works went from version 3.37.1 to 3.39.0, while the version that doesn't work went from 3.38.3 to 3.39.0 (and is now on 3.39.2).

Although I only happened to notice the issue on 3.39.0, two other users have mentioned on the forum that they're having the same issue, one having noticed it before 3.39.0

To Reproduce

1. Click on the "Customize" button under "Email design". It may or may not work for you.
