Hover effect stuck when inside component area

[Ezac]

I'm trying to replicate the hover review system similar to the one used on tripadvisor.

I've done both the 1st and 2nd star as example, I was expecting the hover effect to be disabled when it's no longer on the star but it seems it does not as long as it's in the component area.
