Accidental change of behaviour for electric-layout-mode?

[Morgan Willcock]

It looks like Emacs 30 is now allowing electric-layout-mode to insert
newlines inside comments and strings, whereas previous versions seem to
explicitly stop this from happening.

The commit that does it is b1f8d98a119ab8845d25d80c480cde6e385d8749
(Eglot: rework eglot-imenu) which doesn't mention electric-layout-mode
in the commit message or the associated bug report (58431).

I think it may have been done accidentally and is likely not a backwards
compatible change.

(I actually wanted the new behaviour and only found this because my
tests for newline insertion failed on Emacs 27, 28, and 29.  Making the
new behaviour opt-in would be nice, so I could send a patch to do that
if the previous change does look to have been accidental.)
