I can't remove the element-web reviewer? I don't want to assign for review until ready.

Seems to be locked 🤔

not sure why - was this opened as a draft from the start or converted to a draft?

I think it was created normally. And I see the system note for converting to draft here:

Maybe it's something to do with the code owner but I don't think I did anything to trigger that (edit: maybe not, seems to be the same on other PRs). Usually it assigns element-web but I can remove it.

Now using a consistent offset from both the left and right.

In the before, it was just positioned by the a random ~50px offset from the right side which was a fixed size for all Alignment.Left tooltips regardless of the element size. Now it positions from the actual element.

The v-align is better here but still slightly off, now the tooltip looks a couple px too high

I can change the vertical alignment on this specific tooltip but this probably comes down to the vertical tooltip calculation code which I didn't touch in this PR and also has arbitrary offsets in it. Ideally that code should vertically center things just fine. We can address the vertical problems in another PR because I don't want to keep re-doing the before/after screenshots, etc

It's 20px above and below the read receipt now:

// We don't use `position: relative` on the element because then it won't line
// up with the other read receipts

Removing arbitrary offsets - 16 and + 6

AFAICT, previously this was a logic mistake. Although it worked well enough for all of the icons around the app.

We have the whole width of the viewport, then want to subtract the left position of the element in question to get the space to the right to position the tooltip at.

const left = parentBox.right + window.pageXOffset;
const horizontalCenter = (
parentBox.left - window.pageXOffset + (parentWidth / 2)
);
