[Table block] Edit table actions are unclickable after inserting a new table

[inaikem]

Steps to reproduce

1. Start in WP Admin.
2. Add a new page or post.
3. Add Table block.
4. Specify more than 1 rows and columns.
5. On the toolbar, click on Edit table
6. Click Delete Row or Delete Column
7. Click on Edit table again

What I expected

• User is able to perform additional actions under 'Edit table' menu immediately after inserting a table.

What happened instead

• Edit table actions are greyed out.
• User must refocus on a cell to execute another action.
• The issue only appears immediately after the table is inserted and the edit button is clicked before selecting a table cell.
• If I create a table block and move focus to something else in the editor then click back, a table cell is selected on click/keyboard navigation and the issue is negated.
