Description:
If having frozen headers (rows) and columns in Calc, and scrolling or using an elevated number of rows (around row 19,000), the blue "sqare" around highlighting the acitve cell is not shown, and I can only rely on the highlighted row and column titles. 

Steps to Reproduce:
1. Create a new spreadsheet / LibreOffice Calc file.
2. On cell C3 activate frozen view.
3. Scroll to or use the address box to select cell C18578. No more blue square box showing the active cell.
4. Scroll up some cells, and it is shown again.

Actual Results:
The blue square box on the active cell doesn't show as expected on _any_ cell.

Expected Results:
The blue square box on the active cell should show on _every_ cell.
