VRT

There are some visual changes and bug fixes that were only possible to make in this giant PR. Sorry in advance 😄 I will showcase them below since the PR is large and won't render all images.

before	after	what changed
		inactive icon misaligned
		divider width
		extremely tiny padding change

I have also made the decision to remove a specific VRT test that fails between default and enabled. The failure is likely due to a flex vs grid layout and very minor, and it's not something I can easily "fix" in default. I'm willing to take the risk here.

Looks like this needs to be removed

[langermank]

I've decided to just remove this test because we have it covered with VRT. Our jest config can't read CSS from CSS Module files yet and while we should fix that, I'm not sure its a blocker for this PR.
