Issue:

When entering any keystrokes to edit the file in the text box (to fix any typos, etc), it records a single keystroke and then moves the cursor to the very end of the file in the textbox.

Reproducer:

• Go to https://console.redhat.com/insights/image-builder
• Click on the blueprint and click 'Edit blueprint'
• Click on 'First boot script configuration'
• Click 'Start from scratch'
• Click in the textbox and try to type something

Actual behaviour:

The cursor moves out of the textbox, and the following error is noticed at the bottom:

Missing shebang at first line, e.g. #!/bin/bash

Expected behaviour:

It should allow typing in the textbox without the cursor being moved outside of it.

Additional Information:

So in effect, you really can't edit it but must edit it externally and paste it or upload it into the box.
