User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0

Steps to reproduce:

The grey colour of the "back arrow" button is unthemeable. It disappears with a dark toolbar and light toolbar text but otherwise (dark bar: dark text, light bar: any text) it always remains grey.
the json for the example is this: "toolbar": "rgb(225, 225, 225)", "toolbar_text": "rgb(10, 0, 85)",

Actual results:

The button stays grey, see screenshot.

Expected results:

I would like to see a "toolbar_backbutton_shade" or anything else so I can choose it to at least be not a colour I don't want it to be.

The dark red theme simply has: "toolbar": "black", "toolbar_text": "red"
