Description Andreas Heinisch 2023-03-09 10:04:15 UTC 
Description:
Searching for a specific character in the special characters dialog updates the grid view of the matching characters including unused/empty cells. After the enhancement of Bug 141319, these cells are more visible to the user.

However, if the user clicks on an unused/empty cell at the end of the grid after searching for a specific character, the grid disappears. Clicking on the grid again shows the grid again.

Steps to Reproduce:
1. Open Writer
2. Insert -> Special Character...
3. Search for a character by typing in the search field, for instance "space"
4. Observe how the character grid changes
5. Click on an empty/unused cell at the end of the grid

Actual Results:
Grid disappears. Another click shows the grid again.

Expected Results:
Grid does not change and cannot be scrolled using the arrow keys beyond the used cells.


Reproducible: Always


User Profile Reset: No

Additional Info:
This does not happen if the grid has a scrollbar, for instance, if a font is selected which has unused cells at the end of the grid. 

For instance, select the font "Juice ITC". Scroll at the end to verify the unused/empty cells. The behaviour cannot be observed.

This bug maybe resolved by unifying the implementation of the drawing grids in Bug 154088.
