Cannot edit or remove tabs

Only happens in Firefox, in Chrome it's fine

I believe I have this issue. I have a page where after I add a style (class) to a link , the page saves fine and mu button style is displayed.

Then if I go back to make some further edits, and I click on any of the tabs, the browser completely freezes, I can get no error message from the console. This is in the latest Chrome.

Bootstrap 5 theme.
D 10.3.5
Dev Version:
2.0.x-dev

I was tinkering with he click on the tab link, which is not prevented, and annoys the user by navigating to the #anchor.

I found that preventing the native DOM click event handler, apart from improving UX, seems to fix this bug on firefox!

Attaching a MR to review and test.

MR submitted and ready to review. The only change is the data.domEvent.preventDefault(); line - the rest are just Drupal's coding standards applied to the JS file.
