Has something changed in CSS ?

Has something changed in CSS definitions ?

Only today I noticed. Background color on focused is not working (version 1496) Se example in https://codepen.io/chriscoyier/pen/IgEiz. and below. Rolled back and compiled in an old version as its Ok, with a background color inside when focused.

An example and printscreen (Custom CSS): Same code different results ....

 

input[type=text], textarea {
     background-color: grey;
}
 
input[type=text]:focus, textarea:focus {
     background-color: yellow;
}
