From my tests it has been like that from at least 8.0.7. Couldn't compile on 8.0.6 (something about SplashTheme not existing)

Verified this issue with Visual Studio 17.11.0 Preview 1.0 ( 8.0.40 & 8.0.21& 8.0.3 ) Can repro it. Xamarin form cannot repro it.

If the Label's text is Chinese, there is another issue.

Expected correct behavior, correct line breaks, and the first character of each line is not a punctuation mark:

你好，世
界。

But, Actual behavior，No line breaks and missing characters:

你好，世
