Description of changes

This fixes an issue where the following code input:

<JSX>
  - list item

    <JSX>
      content
    </JSX>
</JSX>

gets formatted like this:

<JSX>
  - list item

      <JSX>
        content
      </JSX>
</JSX>

I'm upstreaming the patch from our repo (with a slight modification for better performance) and the patch worked well inside our codebase.

I've tried to add a test for the change, but the test itself wasn't possible to run in my environment even on main because of the TSC errors of mismatching acorn versions. Maybe it's because of having the lockfile disabled, so the versions diverge? nevermind, looks like using npm forced dependencies to share the same copies of dependencies. Will add a test soon Done!
