Add menuitem to popover menu

[skjnldsv]

Should be useful for occasional popover sub-items (like the upload file menu for example)

Should be useful

So is this actually useful now? How can we test this?

[skjnldsv]

Well in the popover menus, we aim for 'a' or 'button' only children, but since the upload popovers (gallery and files) are using a label to link it to the input file I thought we should add it for compatibility with old apps and for occasional uses like these. :)

you can test it by clicking the add file button on files or gallery (which require some more fixes too)

What happened there? 😁 We definitely have to fix that

We need to get rid of that javascript magic.
