Jumping to nth column command causes the caret to change row when crossing merged cells

[CyrilleB79]

Sometimes jumping to nth column command causes the caret to change row.

Note: to be tested the other way around, I.e. jumping to Nth row should remain in the same column.

Steps to reproduce

• In browser address bar, enter:
  data:text/html,<table><tr><th>the first column</th><th>the second column</th><th>the third column</th><tr><td>@</td><td rowspan=2>a</td><td>b</td></tr><tr><td>0</td><td>2</td></tr><table>
• Go to the cell containing "2" (third and last row and last column of the table)
• Press NVDA+control+1 to jumpt to first column.

Actual behaviour

Review cursor jumps to cell containing "@": second row and first column

Expected behaviour

Review cursor jumps to cell containing "0": third and last row and first column
