You can see that the option correctly shows up in the list, but when selected it's truncated, and there's plenty of space. I can't spot anything in the CSS explaining that width limit.

We also have bug 1480809 on file for another dropdown, so I wonder if there's an underlying problem with sizing these dropdowns.

We've seen this before, but I can't remember *exactly* what caused it. IIRC it had something to do with the internal padding/margin somewhere that caused us to determine the wrong (too narrow) size, with the padding/margin included. I thought we worked around it in the other instance (by moving spacing to a different element or from margin to padding or vice versa), but I could be wrong.

Perhaps Neil can figure out what's going wrong here.

How do I reproduce this? Just use an Italian build?

That, or you might try with pseudolocale

Back to Enn, now that :flod has come back with how to use pseudolocales to reproduce this.

No, I don't see the issue at all.

This is Nightly with accented pseudolocale: this option is fully visible in the dropdown, then truncated.

FYI, this is happening in another dropdown now.

This is still happening in some dropdowns.
