Delete Button for Elements (code, mermaid, callout etc.)

All elements containing larger amounts of text — such as Code Blocks, Mermaid diagrams, Draw.io embeds, Callouts, etc. — can currently only be deleted with the caret once their content has been completely emptied.

At the same time, these elements are often difficult to reliably select with the mouse.

A dedicated delete button on the right side, next to the copy icon, that removes the entire element at once would significantly improve usability. This Button should be only visible on edit mode.
