As the title says. I compared three different email accounts with all three having the same settings on the same machine/browser. What used to happen on all three, and now only two, is once I click an email, and then either click back, or click the X, I'm taken back to the inbox, and the email I was just in would be highlighted like the screen clip below. But this past week one of the accounts no longer does this. When I click back, or the X after reading the email, I'm taken back to the inbox, but no email is highlighted. It's a small inconvenience, but it saved some time when I would want to archive or move the email right after. Now I have put a check in the checkbox to select/highlight the email, and then do what I want to. Anyone have any ideas on why this one account changed this behavior, or how to enable it again? I even switched back to basic, checked settings, but found nothing.

Yahoo email not highlighting inbox email anymore-image.png

So another account started doing the same thing earlier today. After reading an email, and then going back to the inbox, no emails were highlighted. And now the third one is doing it too. Yahoo must be rolling out this "feature". I like it the old way, but at least I know I didn't screw up my email settings.
