I wish that when Text layer gets its text via expression, that all formatting came with it

I have a project with many comps that have similar text in them. I wanted to use expressions to link each text layer to a Primary comp that would control all the other text layers. This way, all the comps automatically have the same text as the Primary comp, and if I fix a typo in the primary comp, all the layers pointing to it automatically update.

The expression I'm using on the "subscribing" text layer looks like this:

comp("PrimaryComp").layer("[TEXT LAYER] 04-TextLayer").text.sourceText

 It works to get the text from the 04-TextLayer in PrimaryComp, but the text formatting doesn't appear the same. 

Hence my wish that formatting would appear in the layers using this expression.
