When I click an email within search results and then click “from” to sort, I lose my place, and the list jumps to the A’s

This is happening only in search results. It works fine when I'm in my regular inbox. For instance, in my Inbox, if I see an email from Sarah, I click on that, then click "From" on the bar at the top, and all the emails get sorted by the sender, but the results jump to the email I highlighted from Sarah. When I try to do the same thing in search results, though, the list jumps to the beginning, and I have to scroll down to see all the emails from Sarah.

I was having other search issues, too, but I was able to fix those by reindexing Spotlight and by installing the most recent update, made available April 1, 2014. This is the last of my three complaints — all things that changed in the last month or so — and I just have no idea how to fix it. Please help.
