New line characters in help for a function argument

[PGS62]

I'm using Excel-DNA Intellisense for VBA functions, which involves providing a worksheet named _Intellisense_. All works great, though I find that new line characters (ascii 10) in the "argument help" have no effect in the intellisense popup. I've tried using ascii 13 and the html tag <br> to no avail.

Is this something that could be fixed?

To illustrate, here's help for a function that parses a .csv file to an array. In the image below, I show the intellisense that I'm able to achieve (on the left) versus what I would like to achieve (with line feeds, mocked up on the right).
