Framer Motion: IE11 Issues

[ItsJonQ]

Looks like Framer Motion is causing IE11 rendering issues:
WordPress/gutenberg#28249

We currently don't use it in many places.. Collapsible is the only one that comes to mind (and Navigator 🙈 )
In that sense, we could remove it 🤔

It would be a shame to lose this library for future animation work.

React Spring is compatible with IE11:

It looks like we're already using it in Gutenberg:

The main component we rely on Framer Motion for (at the moment) is Collapsible.
Replacing it with react-spring would mean writing something like this:

Not impossible.. it's just very manual (not to mention direct imperative DOM style manipulation is required)

Refactoring Navigator will be tricky as well... 🙈

Have you seen motiondivision/motion#781? I don't think that's made it into their docs yet.

@stokesman I have! I found it when I was reading their much larger issue:
motiondivision/motion#364

I could give this a shot 🙏 . Although, we'd have to figure out polyfills still (since they aren't providing them).. and something to do with code splitting?
