Fix scrollbar issues in dropdowns

[silverwind]

See discussion in #10835. @CirnoT: Please confirm this works.

Regarding the help text, I decided to just let it wrap:

(Yes, that border is too bright for in arc-green, but that is for another time)

I think it is strange the menu changes size depending on label size. Short labels make the alt + click text look particularly bad spread across 3 lines

If I make a label with a longer name it looks like the screenshot in the description which is 'good enough'

Then it expands a bit further with a longer name to the maximum size:

Kind of feel it just just be the same size always (like on Github) and perhaps that size should be enough to put the click + enter text on one line.

Issue is that text can expand even wider when localized. I can try some tweaks to get the english version on two lines.

Not sure I like how that "tip" is done in general, it's only on this one label dropdown and not on others. I guess we could also opt to just remove it, or maybe move it to a shared template.

[mrsdizzie]

Could the dropdown just have a fixed width/size like on Github regardless of label text length? I think the tip text is the worst part (and I don't really like how its done either) but also just having the same drop down be different sizes in each place doesn't seem great either but perhaps thats just a preference

[silverwind]

Yeah I guess it should be possible to always expand to the tip width and only ellipsis the actual labels. Will try later.
