Tbh, I ended up intentionally using the native title in a bunch of cases because I didn't like the way the reach one looked or where it was placed. For example the long titles for stack traces intentionally doesn't use the reach title. It's too dark and too large.

I was considering it for hovering the "Suspended by" row too since the reach tooltip placement is unfortunate for that case.

It's especially jarring since it looks very different from other tooltips in the rest of Chrome DevTools.

Why do we need the reach one? Shouldn't we only use native? If not, then we should probably both work on better options for placement and making the styling less strong/work better for large lines.

There are a few examples that don't use the Button nor links and therefore aren't properly accessible.

It enters this mode where tooltips show instantly when you just hovered a TT. There's a smarter name for that behavior. native tooltips don't have that. That's especially useful if you have a items in a collection that all have titles. Native titles also super tiny and can't be styled.

The ones with stacktraces should probably use something else. Maybe even a version where you can hover over the tooltip and select content.

The one in StacktraceView I just missed. If you're ok with this change, I'll go ahead and convert it as well.

We agreed that having the Reach one is better for buttons since Reach tooltips activates on keyboard focus whereas native title doesn't.

For larger areas (e.g. Suspense rects), we'll use native titles since the Reach one uses the bounding box which can be out-of-bounds.

Switching between Reach and title within a related group is problematic since both tooltip implementations don't use the same activation timer. So when you switch from an area with a Reach tooltip to one with a native title, you have to wait a bit before you get the next tooltip. What we want though is that tooltips immediately activate if you just had one displayed. That's the case that motivated this change because I was hovering from Forget badge to No-StrictMode badge and didn't get a tooltip immediately
