Possibly, in some way, resolves #35536
Also resolves #36882

Description

This PR hides the inserter point via the hideInsertionPoint action when the horizontal inserter bar loses focus, or when the mouse leaves.

hideInsertionPoint will not fire when the block inserter panel is open.

We might not have covered all cases documented in #35536, and there is no timeout, but it might help to avoid some of the concerns with the persistent inserter bar.

Try it out today!

How has this been tested?

Take a look at the various scenarios over at #35536

With the right mouse artistry you might find that the bar persists, but, at least in my testing, it doesn't persist as often with these changes.

My goodness, even as is, this feels like a VAST and profound improvement over what's in trunk. As a reminder, this is how easy it is to stick the sibling inserter in trunk at the moment:

Here's this branch:

This feels like a massive forward step. I'd love for this to land as soon as possible! Thank you!

Gave it another spin, and in all my testing I saw no downsides to this one.

The code looks minimal and good. I'd encourage just a quick sanity check from another dev, but honestly this feels good enough to land.

I've started looking at this and I'm not familiar with this code, but I was wondering if you have search for a solution from motion maybe something like onHoverEnd={ maybeHideInserterPoint } in this motion.div?

Thanks for looking!

I tried it out and I don't see any difference in behaviour, so I don't see any implementation issues with it.

Was there a specific reason why we should prefer motion's eventhandler?

Oh, I did find one advantage, aside from the fact that Popover doesn't specifically define an onMouseLeave event: we can perform an equality check on the even target and the current ref to make sure the event is occurring on the motion div.

I've pushed that change since I couldn't detect any noticeable divergence in behaviour.

Thanks for working on this Ramon! It would be great if @ellatrix shared her thoughts here as she has worked a lot with these parts. Should this be better handled here: https://github.com/WordPress/gutenberg/blob/trunk/packages/block-editor/src/components/block-list/use-in-between-inserter.js#L15?

Tried this and I agree is a big improvement. I'm not familiar with the code, so good to get @ellatrix's input if it makes sense in a difference place. Either way this should land once that's done.

Thanks for testing, everyone!

It would be great if @ellatrix shared her thoughts here as she has worked a lot with these parts. Should this be better handled here: https://github.com/WordPress/gutenberg/blob/trunk/packages/block-editor/src/components/block-list/use-in-between-inserter.js#L15?

Yes, I'm also a newbie in this area of the code so would be interested to hear if there's a better way. I couldn't see how we could attach event to the inserter in that hook.

…over, and also the mouse leaves the horizontal line.

Only hiding when the block inserter panel is not open
There seems to be no noticeable difference in behaviour, only that the Popover component doesn't specifically define an `onMouseLeave`.
Also, we can more easily perform a check against the ref and event target.

I removed the onFocusOutside for now, mainly because in testing I couldn't detect any noticeable difference without it.

There is an edge case that this PR does not address: the inserter persists when you click the plus icon and drag your mouse away from it.

This is because there's an exisiting onFocus callback on the motion div that sets openRef.current = true;, which is supposed to indicate that the block inserter panel is open.

LGTM, thanks Ramon! Changes are minimal and make for a way better experience.

I think we can address this in a follow up, as it's already in trunk. Maybe this should be handled in useInBetweenInserter as we are only listening to mousemove event and we could add logic for detecting the dragging.
