@Ziinc - What browser/device are you using?

I am running Chrome 99.0.4844.74 on MacOS and I see the following:

Heads up to everyone, these metadata outputs will be replaced in about a week and will no longer be using Input.TextArea

The scrollable tabs are also doing this, probably something browser-specific we've forgotten about.

I think the best way to treat scroll bars is to just use the default browser scroll bars, the major browsers all have good implementations.

I tried adding custom scrollbars based on light and dark themes and it seems to not support transparency either, so the default browser scrollbars always ended up looking and feeling better (see @Hallidayo screenshot above)
