threshold percentage value seems to be getting ignored

[sjethvani]

I am comparing two images and passing parameters like '--threshold-type' percent & '--threshold' somevalue to Pass/Fail comparison on base of threshold .
However it seems threshold value is not getting honored

D:\>node d:\node_modules\blink-diff\bin\blink-diff --verbose --threshold-
type percent --threshold 0.001% --output compare1.png previous_release1.png next_release1.png
Blink-Diff 1.0.13

Images are similar
386 pixels are different
Wrote differences to compare1.png
Time: 833.052ms
Differences: 386 (0.05%)
PASS

However when I pass threshold as 0% (--threshold 0%) , it works as expected and FAILs comparison when difference is > 0%.
