Why do parameter types in the JavaScript domain have parentheses appended?

[resnickj]

This can be seen right on the Sphinx documentation page for the JavaScript domain: https://www.sphinx-doc.org/en/master/usage/domains/javascript.html

I'm working on a particular set of docs which were last built with Sphinx 3.5, and it did not output parentheses after parameter types. Was this change made intentionally? (I'm not sure why it would ever make sense to have parentheses after parameter type names.) Is there a way to revert to the old behaviour?

Thanks!

Not intentional, this is a bug. Converting to an issue... [#13217]
