Support Meta theme-color for filling the role msapplication-TileColor, bringing back the role of msapplication-navbutton-color (if those meta tags aren't present) and also setting the color of the status bar on Edge Mobile.
And maybe something new like changing the color of the tab itself on the Edge browser.

Chrome has support for this but **only* on Android version, not on Desktop ones

i think it's necceassry
The tile and status bar may not always work as the same color, so maintaining both is probably still a good idea.
