this fix #10453
the fix here is "just" on the "help tool" for straightening with right-click+drag. So it doesn't change anything in params or process.
if rotate and perspective has more than just rotation applied, we can't rely anymore on transformed points. So let's "just" apply the rotation on top of the current one instead.
Note that in this case, we still can have some unexpected result, especially on image borders. This is due to the fact that perspective correction can change with rotation, but we can't really do anything for this case...
in my tests, I've not spotted any regressions, but better double check, as usual ;)
