Comparators stay on when stronger pulse is on the side

The comparator stays on when powering the side with a signal strength of 15 when the back input only has a strength of 14.

I achieved this by setting the delay of 1 repeater and 1 comparator to the side input, as seen in the screenshot, and it only realized to shut off when i right clicked the comparator.

This also works with 2 comparators, instead of a repeater and a comparator.
