Linking Source Text with an expression should also respect the "paragraphness" of the text

Consider this:

I have 3 text layers, two of which are linked to the "master" layer (via a simple "thisComp.layer("master").text.sourceText" expression).

I then change the text on the master layer to be Paragraph Text and tweak the dimensions of  the bounding box. The other text layers do not update to reflect this. I suggest they should do.

Or is there a way, using text attributes in an expression, to copy the paragraph layout?
