Weirdness with toggling comments and reactions with multiple post-type widgets

If you have both a guest book and wall post widget on your own profile at once, clicking the buttons to toggle comments and reactions when making a new post in either one will only uncheck the box on the widget that is higher on the page and not necessarily the one you actually clicked. This happens regardless of whether the checkboxes are visible on the higher widget. As far as I know guest books are the only things you can type in on profiles that aren't yours, so this only really has an effect when posting from your own page. I'm not sure if this is just a visual bug or if it prevents setting this at all on the post. I am on Firefox.

To reproduce this:

1. Put both a guestbook and wall post widget on your profile at once.
2. Move either the guestbook or wall post widgets above and/or to the left of the other one.
3. Click the checkbox of the one that is lower/to the right. You will see the checkbox of the one to its left toggle instead.
