It happens when you have less text than the window height.
This usually happens with a freshly cleared term into which
only a few lines have been written.
If you select more lines than text is on and then you change vertical size of OW
to be smaller than selection -> selection is lost.
Everything is ok if - selection isn't lower than text
- more written lines in OW
Decrease the priority (conditions of appearance are very improbable)
Ivan, could you please look at it?
