Nice, I'm no longer seeing the "ghost widget" issue 😁

Should we also call intersectionObserver.disconnect() to free up the memory?

Sounds good. First time using intersectionObserver, so wasn't aware it needed to be disconnected.

What does IntersectionObserver actually do? There seem to be no docs for it and the name confuses the heck out of me. I don't understand what an intersection might be in this context 😅

It's usually used for lazily showing stuff that's scrolled into view, but also works in this case. The idea is to observe for when the block preview element becomes visible (the widget area is expanded) and only calculate the height of the content when that happens. This was the first time I've had the chance to use it because I've always had to support IE before. 😄

Oooh nice, I didn't realise it was an actual web API!

I'm still seeing scrollbars when expanding a widget area though.
Maybe we need to do something like this:
const height = Math.max(
boundingRect.top + boundingRect.height,
iframe.contentDocument.documentElement.scrollHeight,
);There was a problem hiding this comment.
Haha I was just popping in to say we could use contentDocument.documentElement.scrollHeight instead of the body boundingRect to simplify calculations and get rid of the scrollbar 😄

scrollHeight is how it used to work, but it doesn't take into account margins.
I didn't see any scrollbars in testing, but I guess it needs to be iterated.

The idea was to measure the scrollHeight of the html element, so it includes the margins of all the elements inside, whereas with the body they sometimes collapse out of it.

Ah yeah, sorry, I missed that bit of nuance.

Why removing null? I believe it was served to be the default initial value as the loading state.
Maybe we should just use a loading state here, and set the height directly via DOM API (iframe.style.height).

Ah, ok, didn't notice that. I think using null in that way is definitely confusing. I appreciate the change in #33191, which improves that.

Description
Closes #31935
Addresses half of #31960
The problem was that the code that dynamically resizes preview iframes didn't take into account that all but the first widget area is collapsed when loading the screen. The height was resolving to
0in those collapsed widget areas and not being recalculated when the widget area expanded.This PR does a couple of things:
How has this been tested?
