Steps To Reproduce

1. Insert a 5×5 table.
2. Select the first column from top to bottom — all cells selected ✅.
3. Select the second column from top to bottom — the first cell is not selected, the rest are.
4. Select the third and fourth columns — first cell not selected, rest are.
5. Select the fifth (last) column — all cells selected ✅.
6. Go back to the first column — now the first cell fails to select, rest are selected.

The current behavior

• Only the last column consistently selects all cells.
• Middle columns (2–4) never select the first cell after interacting with other columns.
• First column works initially, but fails after selecting other columns.

The expected behavior

• All columns should allow selecting all cells from top to bottom, consistently.

Impact of fix

• Selection behavior in tables is inconsistent and can break multi-column operations.
• Fixing this benefits anyone working with tables in Lexical (copy/paste, formatting, merging, etc.).
