[MlMt] No longer seeing URL when hovering over links, or link text

[Randall Gellens]

I'm on 10.13.6 (High Sierra) and just updated to 5850 from the released 
5673, and now I no longer get the actual URL pop-up when I hover over a 
link. I also see a large box with an "X" (looks like an envelope so is a 
bit confusing) in place of images and links, and I no longer see the 
link text (e.g., "Click for story"). Are these regression bugs from 5673 
to 5850, or some weird interaction?
