UI doesn't show complete disk models

[dann frazier]

MAAS 2.9.3-beta2 (snap install)

On the storage tab, when a disk model number is of sufficient size, the UI displays a subset of characters followed by an ellipse (see attached screenshot). While that's a perfectly reasonable thing to do when in a constrained space, I don't see a way of getting the full model number from the UI. Expanding the window to provide more space doesn't seem to make a difference after a certain point. One suggestion would be to display the full model number when hovering over that text.
