Selecting all cells "freezes" LibreOffice Calc (when using LO >= 7.3, NVDA >= 2022.1) #13232
Description
Activity
The reason for the freeze is that NVDA calls the
selectedCellsmethod on theIAccessibleTable2interface of the Calc table, which means it requests to receive references to all currently selected cells. Since more than a billion cells are selected, it takes a long time for LibreOffice to generate those...I plan to submit a PR with a potential approach to address this.

Commit 32bf54e ("selection and merged cell announcements in LibreOffice Calc 7.3 and above (#12849)") improved announcement of selected cells for LibreOffice Calc (from version 7.3) on.
As a side-effect, NVDA currently causes a Calc freeze when all cells are selected.
Steps to reproduce:
Actual behavior:
LibreOffice Calc appears to be frozen and doesn't react any more.
Expected behavior:
Calc should remain responsive and some NVDA should make some announcement indicating that all cells have been selected.
