Describe the issue you are experiencing

When typing in remote.send_command commands, if I add a - to add multiple commands HA instantly adds a “null” which can’t be removed unless I hold the delete key for a long time. This persists in safe mode; fully entering the yaml editor does allow normal editing.

Describe the behavior you expected

It shouldn’t add “null” and I should be able to list commands like normal.

Steps to reproduce the issue

Create a button
Remove any entities
Assign Tap action to remote.send_command
Attempt to type in something like

• On
• Off
