Description:
When row/columns are frozen and the calc windows gets resize in a way that the freeze point is outside the visible area, rows and/or columns get unfrozen.

This also happens when opening a file and the stored window size is to small to show the freeze point.

Steps to Reproduce:
1: create new spreadsheet
2: click f20
3: view/freeze rows and columns
4: grab right window border and resize window until the frozen columns are no longer visible completely, and back to original size


Actual Results:
columns no longer frozen


Expected Results:
columns should remain frozen.
Or at least the column freeze should be reinstated when the window is again large enough
The freeze area should not be cleared permanently without explicit user action


Reproducible: Always


User Profile Reset: No



Additional Info:
same with row freeze

when a file is stored/closed with frozen area and open afterwards with a smaller window size this happens also
