What I'm imagining as "correct" behaviour (which sounds different from what the current API will do from your description, but I haven't tested it) is that the user via text-only-zoom mode zooms the text to 1.2x normal size.  Then they switch to page zoom and zoom to 2.0x.  The text should now be 2.4x normal size (or 1.2x the size it would be at the 2.0x page zoom), with everything else 2.0x normal size.  If the text resets back to 2.0x as well (which is what it sounds like you're describing), *that* would be the confusing behaviour in my book.

The most important thing, though, is that if the text zoom was 1.2x before page zooming, then page zooming to 2.0x and then back to 1.0x should leave the text zoom at 1.2x.  Otherwise it's just weird.

I don't have any particular mandate or drive behind this, though, so it doesn't really bother me either way.  Just letting you know how I see it. :)
