FontImage markup extension doesn't allow AppThemeBinding

[davidortinau]

Description

This works in Hot Reload, but won't compile.

<Button Text="Comment" 
                            Background="Transparent" 
                            TextColor="{AppThemeBinding Light=Black, Dark=White}" 
                            ImageSource="{FontImage Glyph={x:Static f:FontAwesome.CommentAlt}, Color={AppThemeBinding Light=Black, Dark=White}, FontFamily=FontAwesome, Size=18}" />

This works everywhere:

<Button Text="Comment" 
                            Background="Transparent" 
                            TextColor="{AppThemeBinding Light=Black, Dark=White}" >
                            <Button.ImageSource>
                                <FontImageSource Glyph="{x:Static f:FontAwesome.CommentAlt}" 
                                    Color="{AppThemeBinding Light=Black, Dark=White}" 
                                    FontFamily="FontAwesome" 
                                    Size="18" />
                            </Button.ImageSource>
                        </Button>
