Automatically open selection in other editor - setting doesn't persist

In RC7, working happily with project corkboard open in one part of a split editor, after clicking on the tiny icon in the footer bar, clicking on an item correctly opens the document in the other editor.

If I unsplit the editor temporarily and then re-split, the ‘automatic selection’ setting has been canceled. This was not the case in v1.9 where the setting persisted (I just rechecked - prefer the double arrow icons in v1.9 :slight_smile: ).

Is this change in behaviour a desired design feature or a bug?
