[fix] Prevent empty UI when deleting a table

[aarab002]

Description

This PR fixes the UI/UX issue where deleting a table via “Edit table → Clear data” followed by “Edit table → Delete” leaves an empty, non-interactive box instead of reverting back to a blank text area.

The issue occurred because the table component remained mounted after deletion without notifying the parent renderer to switch back to text mode.

Thanks @aarab002! I'll likely need to mid-next week to test it but on a quick glance it looks good.
