Description

For a very small change in a large area with mismatchThreshold set to 0, the diff is not detected:

However when a bit more of the component is changed the diff is detected:

I'd expect any difference to be detected when mismatchThreshold is set to 0. Any help on this would be much appreciated. Thanks.
