I believe in L5 when one clicked inside of the reference window, the contents became selected, and a user could simply type a new reference

However, in L6, when one clicks in the reference window, the contents briefly get selected and then deselected. One has to either double-click again, or do click-and-drag to select the reference.
This is a regression which makes using Logos more time consuming.
