Fix overflowing selected of options

[susnux]

Currently if the width of the select element is not enough the selected option will overflow the element, even if the inner component of the selected option slot has some overflow rules set (like ellipsis).

To fix this, both the selected option and the container needs to reset the min-width.

before	after

Especially note the actions are missing before, as they were placed underneath some elements outside the select on the right.
