FloatingFocusManager focusout handler - closes when clicking another button, does not close on outside click

I created a small reproduction in a branch in my fork: https://github.com/mihkeleidast/floating-ui/commit/c5b92d4b029d8902e5b5a3178cb4cb4b3072ad37

Ran across an inconsistency in how the focusout handler works. Two different scenarios at play here:

Scenario 1

1. Open Popover from the button
2. Click outside of the Popover, observe that it does not close
3. Click the “Second button”, observe that the Popover remains open

Scenario 2

1. Open Popover from the button
2. Click the “Second button” observe that the Popover closes

As far as I debugged, the focusout handler fires in both cases when clicking outside of the floating element, but in scenario 1, when clicking the background, relatedTarget is null, so it does not fire the open change event.

It is kind of an edge case, but would be good if the behavior was consistent, to know what I should expect, as from the users perspective a random click outside should not change anything.

Some additional info: in my real usecase, I do not have such Popovers, rather it is a drawer-like component (ex https://shoelace.style/components/drawer) that can be configured to not render on top of other content, rather it would render aside the main page. In this context, I have floating-ui configured to not close the floating element on outside click, but this issue means it still does in some cases. I can create a more realistic sandbox, if necessary, though I think the above describes the issue in enough detail.

I would go with the first, to allow disabling the focusout behavior, for my usecase this solves more problems actually - I’ll try to put a PR together with a testable example, if that sounds good?

So I guess we have two options:

• Add a prop that allows the user to disable focusout behavior.
• Detect if a pointerdown event occurred on the related target right before the focusout occurred, if so prevent closing. Keeps keyboard/virtual cursor closing working.
