[Bug][iOS] Custom font not rendered when Label.TextType="Html"

[davidbritch]

Description

The following code uses a custom font, registered with the ExportFont attribute, and works perfectly:

        <Label Text="Hello Forms with XAML"
               FontFamily="Lobster" />

However, when the TextType property is set to Html, the custom font isn't rendered on iOS:

        <Label Text="Hello Forms with XAML"
               FontFamily="Lobster"
               TextType="Html"/>

Steps to Reproduce

1. Run the attached sample.

Expected Behavior

"Hello Forms with XAML" is rendered using the custom font.

Actual Behavior

"Hello Forms with XAML" is rendered using the default (plain) font.

Basic Information

• Version with issue: 4.6.0.726
• IDE: VSMac 8.5.4
• Platform Target Frameworks:

Refering on #2802 bug, my assemblyinfo file is currently using an alias like this:

[assembly: ExportFont("CircularStd-Bold.ttf", Alias = "FontStdBold")]

We have faced a similar issue (probably the same) on one iOS project and pulled together a sample to reproduce the issue. Basically the issue is reproduced even without using a custom font, even basic attributes are not applied (e.g. FontSize, TextColor) when TextType=Html. And it works for Android as expected, please see below:

The sample project is below:

Waiting for this one to be fixed. Very important for my project. :(
