Steps to reproduce the problem:
1. Open a new tab
2. Type chrome://gpuhang
3. Press the Enter button

What is the expected behavior?
chrome://gpuhang is supposed to hang the GPU process for a few seconds before the GPU process is killed.

What went wrong?
chrome://gpuhang produces the same result as chrome://gpucrash. chrome://gpuhang just kills the GPU process.

Did this work before? Yes N/A
