Sort column in 'files in working tree' keeps resetting

Since I installed 1.6.4.1, I've noticed that the column I'm sorting by in 'Files in the working tree' keeps resetting itself to 'Filename'. I prefer to sort by 'Path' and I'm sure that in older versions, this preference was remembered between sessions.

Now, every time I open a repo window, I have to reclick the Path header to sort by that column again. This is annoying and a bit of a regression, I'm certain I didn't used to have to do this. Maybe this is a consequence of change SRCTREE-1440? Could this behaviour be put back to how it was before, where the previously sorted column is remembered?
