White text on white background in Edit Data JSONB column

I am using pgadmin 1.20.0 on Windows 10. When I am looking at my table which has a jsonb column, if the contents of a field are long (in my case the field is 22k of JSON), the text is not visible in the appropriate cell until I click on the cell and drag left or right. When I do this (ie. highlight the text with the mouse), the text is legible (black text on white background).
