Google Font and Editable Cell

I installed a Google font (Bellefair, size: 18 pts), run a project, work with it during some times and when I had to make a change, I double-clicked on a Cell to edit its contents.

Surprise: the ListBox contents scroll up, and display the Edit Cell far below its real location (watch the image below).
