I have open 5 (equal width) panes in the Accordance 12.0.2 workspace (15.4" retina MBP). When I change commentary in the second pane, combined tool icon gets offset, and is displayed on top of the font size adjustment icons. See the attached screenshot. If I click combined tool icon and add another commentary there, icon is moved back to where it should be.
P.S. This problem was already in v.11, now it has moved over to v.12.
