Text color contrast is barely readable for Pipelines visualization/graph page with Roboto fonts
Summary
Job titles on Pipelines graph/visualization page are barely readable under Roboto fonts, this is probably due to how font-weight is treated across different system fonts.
Steps to reproduce
This is applicable only to OS having Roboto fonts installed as used as default by browser. Below screenshot was taken on Chrome running in Ubuntu 16.10, using Roboto as default system font.
Expected behavior
Job titles should have better contrast with page background such that text is readable.
Actual behavior
Text color is so light that it is barely readable.
