[Client] Jumbled Mastery Pages After Reordering

If I adjust the position of multiple mastery pages without leaving the view, they appear to be ordered correctly. If I return to my mastery pages after looking at a different view, they appear to be somewhat jumbled.

I was able to order them appropriately by leaving and re-entering the Mastery view after every individual change.

I'm not sure how positions are determined/stored, but it doesn't appear to work properly when multiple pages have their order changed.
