[Desktop] When the Mac dark theme/mode is active I can barely see the dark blue text/urls in the address bar

I've a similar problem to this one: #9945
When the dark theme/mode is active I can barely see the dark blue text/urls in the address bar.

The color contrast is very very low (dark blue on almost black backgrounf), even for a "normal" person: for people with problems it probably looks all background with no urls.
