Notice the difference in font size between the main text, the verse reference, and the verse text in the pop-up. (The actual resources here is BDAG, looking at the article on ὑπόστασις. But this occurs in other resources as well.)

This was done with Default Text Size set to 140% and Set New Display to No - though it looks the same with Set New Display to Yes.
(Sorry if this was mentioned elsewhere. I have not kept up with all the posts in this thread.)
