None of the code currently uses the way you are doing tooltips.+
I'd like to not add more entropy like this.

Please add a helptext (like for the other fields) instead.
The short helptext should:

• explian what this field does in terms of where we use it
• and that the content is sanitised.

Thanks. Now idiomatically showing helptext similar to other fields. Not sure if the text is too long. Thought I should mention spaces and indentation being preserved as highlighting that was the motivation for this fix. Let me know if it works.
