Isolation routing does not appear to respect the overlap setting for the last path in the middle of two copper areas.
For example in the below image overlap is set to 49%, tool width 0.25 mm and the gap is 0.5 mm:
The overlap between the two 0.25 mm routing paths is in fact 0%, not the 49% requested. This often results in thin slivers of copper being left behind if the tool width is not perfectly accurate.
