Steps to reproduce the problem:
Chrome doesn't understand this:

  filter: drop-shadow(0px 2px 2px rgba(0, 0, 0, 0.14)); 

but it does understand this:

  -webkit-filter: drop-shadow(0px 2px 2px rgba(0, 0, 0, 0.14)); 

What is the expected behavior?

What went wrong?
When are we going to remove the "-webkit-" prefix from CSS filters?  Every other major browser has removed them:
