It's just a bug introduced recently.

I have ben using the DiffTool class for a while. However recently it
stopped working.
In the window, the left-hand gutter gets populated with diff bars,
but not the right-hand panel. It gets one bar at the top, which
populates the gutter
when clicked on. Is DiffTool no longer supported?
