UPDATE:
I thought I had solved this problem by altering the value of
vedautosave_preserve.
But it now turns out that I was misled because after that mishap has
occured while editing a file, if I continue editing it doesn't occur
again in that session! I don't need to change any variable values.
And altering vedautosave_preserve doesn't help as thought it did.
I don't think this depends on selinux, as I have disabled it on this
machine. Also I would expect selinux to abort the whole process, not cause
its internal state to be changed from editing to not editing.
I did not have that problem running the latest poplog on an older machine
running fedora 29, only my new machine running f32.
I guess I'll just have to go on looking for a pattern that I have not yet
noticed.
