UI colors for NGE leaking to NME

[PatrickRyanMS]

The UI accent color in NME is blue and in NGE is green. However, when there is a PG with both node geometry and node material components, the accent color is the green used by NGE for both editors. There is something leaking between the editors in style.

This playground repro has both a node material and a node geometry, and opening both editors will display green as the accent color.
