I'll be supplying more details soon

Looking at M33, and then this I think you've got the labeling for hover, and focus mixed up.

Started implementing parts of this in OOUI - https://gerrit.wikimedia.org/r/#/c/209190/

Normal	Hover	Open

While doing so I realized that I was implementing DropDownWidget and not ComboBoxWidget
@violetto, could you please add specs for that in this pholio itself? I'll start work on ComboBoxWidget as well.

About blue outline on hover for textfield:

Remember how we have this on focus?

It'll be more consistent if on hover it becomes blue with 1px border and then change to 2px on focus. So the change of color isn't jarring.

For every single text field that we have going forward, they will adopt the same blue style.
