LineBreak() not working with FormulaMap()

1

LineBreak() is not working with FormulaMap(). Neither Char(10) and Character(10) are.
It used to work before. Is it a bug?

list(1,2,3).FormulaMap(Concatenate(CurrentValue,linebreak())) returns 1, 2, 3 with no line break.

The only way I get it to work is this way:

list(1,2,3).FormulaMap(Concatenate(CurrentValue)).Join(LineBreak())

What if you did:
list(1,2,3).join(lineBreak())

Hi @Scott_Collier-Weir. It does work this way, but that was only a simplified version of my formula that I did just to prove my point.
It was something that was working before and not working now.
I did a dummy doc to demonstrate it better.
