Work around (not bug fix) for issue #684.

[ntoll]

Description

Fixes ##684.

This was an adventure. After exploring a Qt rabbit hole I proved my hunch was correct (the size of the QLabel wasn't being redrawn when the setText method was called, hence the truncated text). Investigating a workaround ended up with the first commit which was created because I was unaware of the adjustSize method on the QWidget base class. However, once I found it, I scratched by work-around approach and now it works. :-)

Test Plan

None (needed).
