Steps to reproduce:

I used an inset box-shadow with a non-zero blur radius:
box-shadow: inset 50px 0 5px 0 red;


Actual results:

The box shadow is drawn incorrectly.

Expected results:

There should be 50px of solid red starting at the left, but it mostly disappears once the blur radius is raised above 0.

I can repro the issue too. We also have old pixel difference test results to demonstrate that this regression was introduced after 43.0. Old goldens from 43.0 look fine, but we found the issue when our testing infrastructure moved to v. 44.0.
