APEX v23.2
To make the column header break onto 2 lines

I have used:

This works fine however any generic APEX validation messages also display the tag:

Ideally I could get rid of the <br> in the heading and make the column header totally responsive so it wraps when the column size is too small so if there's a way to do that, that would be great. Otherwise need to get rid of it in the warning.
Any ideas?
Thanks,
Lee
