Steps to reproduce:

1. Load https://en.wikipedia.org/wiki/List_of_largest_cities
2. Move to the second table (with 84 rows and 14 columns containing the list of largest cities)
3. Use table navigation commands to move around the table:

• control+alt+arrows to move by one column
• control+alt+page up / down to move to top or bottom row
• control+alt+home to move to first column
• control+alt+end to move to end column

4. Try the same on a table in the NVDA user guide

Actual behavior:

Everything works fine when testing with Chrome, and everything works fine testing with NVDA 2022.3.2.

Everything works as expected in the user guide, and everything works in the wikipedia table except the move to first column command, control+alt+home.

This command generates the following in the log:
