Bug 446783 shows that the Tool Options docker can be pathologically resized into unusability. This is because its sole child is a QScrollArea, which by its own nature is sizeless.
We need to decide what to do with it:
- Do we set an arbitrary, but reasonable minimum size?
- This was shot down in MR !1288
- Do we instead ensure that all its child widgets are reflowable?
- This is a far more complex undertaking, there are a lot of tool options widgets, and some exist in code only.
