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).

This is annoying as the field appears blank until I highlight it. With a
short piece of JSON, there is no such problem.
