BlazorWebView CSS is only applied to Windows app but not Android

[sturlath]

Description

I have this code base (file new project today from 17.2.0 preview 2.1 on Windows) where I added some CSS to try out and it works fine when run on Windows Machine but not if I try it out on a Android device

Looks good on Windows

But this is how it looks on my Android device (Samsung Galaxy S7 (SM-G930F))

Steps to Reproduce

Try out my code on an Android device.

Thanks for the report and linking your code, however either your repo doesn't exist or it's set to private :)

[sturlath]

Sorry @jfversluis it was private 🙈 you should now be able to view it.

Reproduced CSS not working on Android 11, VS 2022 Professional 2022 (64-bit) - 17.2.0 Preview 2.1

And moreover - Android 5 gives this error:

[SteveSandersonMS]

@sturlath Thanks for the report. To narrow this down, could you please try the following?

• Try running this in the Android simulator with the newest device you can. It might be a limitation in CSS support on your Android version.
• Try to reproduce this using the same HTML/CSS plain MAUI WebView (not BlazorWebView). Does it also happen in that case?

I works on a Nexus 10 - API 30 emulator I had (so I guess it should work on others)

I´ll try to create a new project (with same CSS/HTLM) and see how that looks on the phone (I´m guessing you are interested in that right?). I´m sure I can manage to find it out in the next few days. Any change you could point me to a example repo that I could then plug my CSS/HTLM in?
