Previous search term displaying in search box when using Command+F

Not every time it appears. I just did it several times, and yes, it would automatically highlight the previous search text as long as I don't click on anything. If I click on an entry and then do command+F, it will place the text insertion after the previous search term.

I also see it does this if you first click into a tag from the sidebar. However, I see the value in that because then you can quickly search inside just that tag.
