SetStringParameters() was called during widget tree init in the constructor.
Calls within a constructor cannot call the derived classes methods. This would result in invalid data being passed to the string system, which could then crash.
(cherry picked from commit fef0bfcfd3)
Empty area at the top of some textfile windows due to calling
SetDisplayedPlane() after calling FinishInitNested(), and/or changing
the displayed plane and not calling ReInit() after.
This was previously hidden by CheckForMissingGlyphs() reinitialising
all windows anyway.
