Describe the issue you are experiencing

Moved from integration to frontend
Original issue: home-assistant/core#136515 (comment)

I noticed an automation was not working as intended. I expect it is due to a whitespace at the end of the trigger ID.

It would be nice if whitespace would be automatically removed or ignored since I cannot imagine anyone wants to use this whitespace.

Describe the behavior you expected

Whitespace is automatically trimmed from Trigger IDs.

Steps to reproduce the issue

1. Create a trigger with an ID with an accidental whitespace at the end
2. Use the trigger ID as an condition in an action.
3. Observe how the action's trigger ID does not match the trigger's ID.
