Steps to reproduce the problem:
1. Use dark theme in DevTools
2. Open Performance monitor

What is the expected behavior?
I can read the text for the value for JS heap size fairly well.

What went wrong?
The color of the text is blue with a background #242424, resulting in a very poor contrast ratio of 1.81.

Also CPU usage is below the AA limit (3.88), as well as other (hidden by default) lines:
* Documents (4.20)
* Layout / sec (1.45)
* Style recalcs / sec (3.58).

Did this work before? No
