pgAdmin 4 v4.16 query tool window overridden with text, scroll bar too tiny to be usable

Running pgAdmin 4 v4.16 under Chromium on Windows 10 Enterprise.  Unfortunately the query window (see below) seems to be suffering from a couple of major issues.  First, wide text overwrites the right side of the window and second, if there is a *large* number of lines the scroll bar itself shrinks to unusability.  This coupled with the lack of arrows at ether end of the scroll bar means that you are left to blindly clicking.
