Hi Daniel,

sorry for getting back so terribly late, I somehow failed to notice the
email and didn't use Emacs for JS much in the past year. But I'm using
js-mode intensively again from now on, so the issue has become important
for me again.

I disagree, it's a very popular style and I'm using it all the time.
Many others do, look e.g. at the jQuery code:
https://github.com/jquery/jquery/blob/master/src/core.js

True, but it's still very irritating to have Emacs indent it incorrectly
every time you insert/edit such a statement and having to manually fix
the indentation. That's why I used other editors for JS in the past
year, but I really want to use Emacs, so I'm back.

I did have a look at the code, but I'm not familiar with font-lock, so I
couldn't fix it. But I'd be very happy to help with the more general
highlighting scheme.
