To clarify: we’ve tested this on 2.3.8 without plugins as well as our 2.3.3 production env. and the issue is reproducible in Chrome and Safari, it actually crashes the tab in both.
A patch to 2.3.8 would be very nice for us, at the moment we don’t have the budget available to upgrade to 2.4.x (we’re running quite a bespoke plugin setup; so small things tend to break a bit when upgrading major versions).
