FreezeRowB1.ods (test data)
If a frozen-row includes a folded outline-group, when user unfolds that outline-group and that causes the frozen-row to shift outside of the visible pane, then all rows become unfrozen (scrollable).
Same symptom happens for columns as well.
Once the frozen-row has been reset by this way, saving the sheet and re-opening the file maintains the symptom.
Steps to reproduce:
1. Adjust LibreCalc window to show only A1:J41.
2. Select rows 2:40.
4. Press the "-" button on the left edge to fold the outline-group.
5. Select cell B50.
This is the attached FreezeRowB1.ods
Screenshot on my PC is FreezeRowB1_ods_screenshot.png
7. Press the "+" button on the left edge to unfold the outline-group.
Now it looks like this: FreezeRowB2_ods_screenshot.png
8. Try vertical scroll. No row is frozen anymore.
9. Press again the "-" button on the left edge to fold the outline-group.
10. Try vertical scroll. Still, no row is frozen anymore.
At step 7, frozen rows should be kept frozen, with the visible top left cell should be A1, like the attached FreezeRowB3_ods_screenshot.png.
After step 9, rows above cell B50 should be frozen, ie. should not be scrollable.
Reproducible: always (tested over 10/10)
User Profile Reset: No
Seems sometimes irreproducible when window is small, eg. only 10 rows.

(In reply to Buovjaga from comment #4)
You did not reproduce on linux, that may be becaue on Linux when the outline is expanded the range did not exceed the visible area.
I do reproduce this on Linux with a recent master build.
May be a duplicate of bug 120117, but I am not sure, thus adding to SEE ALSO instead.
Yes, it seems this is required to reproduce "Adjust LibreCalc window to show only A1:J41."
