Due to some weird combination of circumstances, when I open LO in LXQt (of Lubuntu 20.04), the window is often tiny - less than twice the cursor size in height and of essentially-zero width - and located at the corner of the screen, so it's easy to just miss altogether. When this happens one needs to notice the window is not actually missing, and carefully place the cursor on its edge to resize it.

This makes me think that perhaps LO should perhaps "resist" being opened with too small of a window size. So as not to be too extreme, we could allow resizing it to make it very small, but when a module window is first created, either communicate some minimum dimensions to the window manager, or otherwise self-resize to such minimum dimensions.

I didn't mark this as Linux since, in principle, it's an issue on other platforms
