Comment (by gziolo):

 > Was this specifically added for Safari < 15? Do we even support that?

 As far as I remember it could be tested in Safari 14 but the same issue
 existed for other browsers as listed in https://caniuse.com/mdn-
 html_elements_script_type_importmap. The browser support is at 90%
 overall, but I'm not entirely sure how to compare that with what WordPress
 officially supports.
