If you have mixed font styles such as Bold, italic etc, they are overwritten if you change the size of the font. Even if the fonts are all the same size. If you have tracking or leading, it overides your layout work.
I sat with a client doing manual font work on size, bold/medium, tracking etc. Then additional client feedback came in, asking to make the fonts bigger. Doing so removed all the prior work!

It shouldn't do that. It should only change the size of the font. Leaving all formatting alone.

Text, Text+, or both?

Yes, I can confirm in Text. Font Face and Tracking of separately formatted words or characters get reset when changing the Size parameter for all of the text. As a workaround until this gets fixed, use the Zoom parameter instead.
