No further selections can be made in Source mode after selecting an entire table cell when editing in-place

STEPS TO REPRODUCE

1. Create a page
2. Insert a table (e.g. 3x3) with some values in its cells and Save
3. Edit the page in-place
4. Click on 'Source'
5. Select an entire value from a cell (all cell content)
6. Click on 'Source' to switch back to WYSIWYG
7. Click on 'Source' again
8. Select another cell value or just another word outside the table

EXPECTED RESULTS

The selection can be made properly.

ACTUAL RESULTS

Nothing can be selected anymore in Source mode.

The issue can be reproduced also by simply selecting some entire cells (not just their values) in WYSIWYG mode and then switch to Source.
