Sequential Pin to the Top doesn't work

Problem description

Please describe the issue concisely in here. In case of an error: Walk us through the steps you took to get there. What happened? What did you expect to happen? If you have a hierarchy of tags. Say AK_Step1::SketchyMicro::Parasites. If you pin Sketchy Micro to the top, that works. However, if you then go on to pin Parasites to the top that doesn't work. It is bolded, but it retains its current position. If you then unpin SketchyMicro, only then does Parasites get shifted to the top. I'm using the latest beta version of Anki (2.1.24 Beta 8 on the Mac).

Here's a picture to show you:

If I go on to Unpin SketchyMicro, then you will see Parasites goes to the top.
