I did some more testing using the latest Previewer release (3.9). Books will fail to support Enhanced Typesetting if the media queries cause the visible content to differ by more than about 5% between the MOBI and KF8/KFX versions.

I have attached a test file to demonstrate this. As is, it will convert properly using Previewer 3.9. But if the second paragraph, with repeated "Mobi only" text, is made about 10 characters longer it will fail to convert.

(Edit fixed minor problem with attachment.)
