No symbol shown beside 'Home screen installation'

[gytdau]

The 'Home screen installation' item under 'Behave like a native app' has no tag.

If not having a tag was meant to convey 'this item is not applicable to your system', then a question mark symbol might do a better job instead.

Not having a tag conveys "There's no way to check if your browser supports the feature". I don't want to do browser sniffing as it requires constant updating and I find it inaccurate and there is no way to detect the support otherwise, as I linked in the similar issue. In which way the question mark would be somehow better than not having any icon at all?

[gytdau]

I was thinking that you could have a blue question mark in a circle and then add that in the legend as something along the lines of 'Unknown support'. It's better than nothing, and it provides a bit of context instead of having no icon.

Same on Macintosh Safari, Firefox and Chrome.

Solved with window.BeforeInstallPromptEvent test.
