Strange CSS for sidebar field captions

[johannahoerrmann]

When hovering over captions of fields in the sidebar, a question mark is shown (cursor: help). Why?

I believe this was changed in 2.2 because a max-width setting was introduced. Hovering over the caption text then made the whole caption appear. I think the help cursor is just because captions are usually associated with some helpful information about the field.

I'm sure @eKoEs or @nilshoerrmann can clarify though :)

@nilshoerrmann was asked before posting.
@nilshoerrmann said he doesn't know why.

Yep

Yep!

The only problem is that the question mark is shown even when the respective caption isn't truncated by default, which might be confusing.

Do we still consider this as an issue? An idea to remove the question mark might be to write a few JS lines that check if the given caption width is below the max-width value. In that case, we remove the question mark by adding an extra CSS class.

Couldn't we just remove cursor: help;. I only see it when hovering over the caption and then the full content will be shown immediately (there is no additional action required and nothing additional will be shown – like a pop over or something similar).

Yeah we can remove it, it's not that useful after all.
