Only two tabs scrolled, so the rest handed their full content height to
the window as a minimum. The API tab alone asked for 668px, which put the
window's minimum at 756px: taller than a laptop screen has room for once
the menu bar and dock have taken theirs, and unshrinkable, so Save sat off
the bottom edge. Every tab scrolls now, and the opening size is clamped to
what the screen actually offers.
The program path in the local model box was clipped to one line for a
related reason: it shares a form row with a button, and the row is
measured before its width is known. WrappedLabel re-measures against the
width it ends up with and claims that height back.
