Please review the following checklist.

• Updated CHANGELOG.md (where appropriate)

Looks like the scrollbars have a rather sickly yellow color. I'm guessing because colors that were previously ignored are now updated?

You might need to change the defaults, to restore the original look.

[rodrigogiraoserrao]

@willmcgugan I only get that “sicklish” tone when scrollbars are being hovered and I thought that was the default styling for scrollbar-color-hover (which was being ignored).

Here is a screenshot: on the left, I have my mouse over the scrollbar (which also means that I do not have my mouse over the scrollbar on the right).

What color would you prefer, instead, for scrollbar-color-hover?

[willmcgugan]

Same color as before this update, which I believe didn't change the scrollbar thumb at all...

[rodrigogiraoserrao]

Yes, before this update the scrollbar thumb wasn't updated when the scrollbar was hovered.

Upon hovering a scrollbar, do we want the default scrollbar-color-hover to match scrollbar-color or do we want it to be explicitly that specific shade of blue?

[willmcgugan]

Set it to the same shade should be fine. It still allows custom CSS to override it if desired.

Looks good!
