ui: recent build dropdown doesnt support select/copy

[plyr4]

Description

see title.
i think you should be able to copy content from the recent builds hover tooltip, but sadly the tooltip goes away before you can highlight any of the content because you arent hovering it anymore.

Value

better user experience, easier to debug and share details (like which worker the build ran on)

Solution(?)

we can probably just apply the hover #ID to the build icon element AND the tooltip element, instead of just having it on the build icon. that way the hovering works the same for both elements and fades away when your mouse is not on either of them.
