Comparator does not react, as it should

What I expected to happen was:
Comparator should be blocked by a stronger signal from the side input when it is powered by a weaker signal from the main input

What actually happened was:
When main input is powered, changing the side signal to stronger than the main input does not affect the output. However, if you block comparator at first it stays blocked until you update the main input

Steps to Reproduce:
1. Put a Comparator
2. provide signal at the main input
3. provide stronger signal on the side input

DOES NOT WORK PROPERLY

Steps to Reproduce:
1. Put a Comparator
2. Provide signal at the side input
3. provide weaker signal at the main input
4. turn off the side signal

DOES NOT WORK PROPERLY
