Text Overflow Fit Multiline Issue

When adding line-break characters to a Text Run that has Overflow set to Fit, the Text is scaled as if it was on a single line.

I would expect the text to fit with regards to line-break as well, so scaling to fit the widest line on the horizontal axis.

This seems like an unintentional issue that we cannot work around as users with using dynamic (on runtime set) Text Runs with variable copy.
