Normally the website will override background or background-image which is why our autofill styles disappear, but best buy is using the -webkit-box-shadow which makes the background-image not appear but doesn't overwrite the background-image rule in the inspector. Using the background-color/background rules in combination with box-shadow/-webkit-box-shadow seems to work as expected outside of the input:autofill selector so I'm not sure why there's a clash here. Oh, figured out why.

So best buy is using a box shadow with the following parameters: 0 0 0 0px #fff inset. These 30px of white inset are a higher z-index than the background-image causing the yellow highlight to disappear when it's really hidden behind the box-shadow insert.

:emilio, I don't think this is urgent but is there any way to prevent an inset box-shadow from hiding our autofill background-image? I'm guessing we could set like a z-index or something on the input:autofill, select:autofill selectors but I don't think that's necessarily the right way to go.

We could do this in the painting code. Changing the z-index is not an option, the shadow is inside the input. But it might be problematic since that would disable otherwise-benign shadows as well.

This is specific web site desire to interfere with autofill styling. We won't be fixing this one.
