Playing around with this locally and it's just excellent. I've modified a little CSS here and there for the hover and make it clearer where the widgets start/finish, even when not hovered.

6 x Slider E2E failures, which is very odd and potentially overlaps with the issues we've seen in the Slider tests with #1488 too

Yes, as #1488 is based off this branch (since it affects an area re-written in this PR and I didnt want to fix the HTTP issue twice)

The problem most likely lives in this branch.

Invistigating.
