Comperators sometimes dont work properly.I think it is a bug

1.experiment

Steps to reproduce: build redstone circuit Screenshot(180).png

observed result: no redstone output from the repeater

expected result: redstone output from the repeater becurse the signal that goes into the side

of the comperator is weaker than the one at the front.

2.experiment

Steps to reproduce:build redstone circuit Screenshot(179).png

observed result: the repeater now puts out a redstone signal becurse the comperator now works like it is intended

result: The comperator behaves different in this 2 situations even when it gets the same redstone input.
