      Description

      When adding widgets to a layout "later on" (so not in the constructor), the minimum size hint of these widgets is ignored. It is possible to shrink the window much further than should be possible.

      1. Create a QWidget, give it a layout. Connect QTimer::singleShot to a method that will add widgets to the layout. Resize the window as small as possible.
      2. I expected the window to stop getting smaller once the minimum size of the contained widgets is reached.
      3. The window keeps getting smaller.

      I have verified that this issue exists on Linux, Mac, and Windows.

      Code to reproduce the issue:
