Unexpected cell selection behavior in tables

[SeniorSpielbergo]

Describe the bug
Cells in the table block seem to only accept selection when clicking in a specific area of the cell. Especially when writing longer texts, the issue becomes particularly apparent. The area seems to align with the part of the cell where the cursor appears when correctly selecting the cell.

To reproduce
Steps to reproduce the behavior:

1. Create a table block with at least two cells.
2. Add an example text to one of the cells. Especially when writing longer texts, the issue becomes particularly apparent (e.g., "Short example text to demonstrate unexpected behavior when selecting other cells in the created table. Short example text to demonstrate unexpected behavior when selecting other cells in the created table. Short example text to demonstrate unexpected behavior when selecting other cells in the created table.").
3. Optionally activate the "Fixed width table cells" option. However, this option does not change the unexpected behavior.
4. Select any of the other cells. Hovering with the mouse cursor over / clicking in different parts of the cell demonstrates that only a small area is actually accepting clicks to select the cell for editing. Compare with the areas highlighted in green and red in the attached Screenshot 1.

Expected behavior
As long as the user clicks somewhere in the rectangular area of a cell, it should not matter where the user clicks to select the cell for editing.

Screenshots
Screenshot 1: The green area seems to accept clicks by the user. The red area does not accept clicks by the user.

Thank you for reporting this issue, I was able to reproduce the problem in the last version of Gutenberg 5.8.0.
