        <pre>Description:
When a sufficient amount of cells (6 on an old laptop, ~20 on a recent one) are
selected in 5.4.4.2 there is an increasing delay when selecting new cells until
Calc freezes.

It happens with or without OpenCL enabled.

I can't reproduce it with 6.0.0-rc1.

Steps to Reproduce:
- Open a new spreadsheet in calc.
- Hold CTRL
- Click on empty non-adjacent cells to select them. The slowdown happens around
20 cells selected.

Actual Results:  
Calc slows down and freeze

Expected Results:
The selection of new cells should not freeze Calc.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes
