Custom font does not apply to RemoteViews in ongoing notification

[Mb8383]

Description

I am using .NET MAUI to create an ongoing notification on Android. The notification's layout is defined using RemoteViews, and I am trying to apply a custom font to a TextView inside the RemoteViews.

However, the custom font is not applied at all — the text is always displayed using the default system font. I have verified that the font is correctly added to the project and works fine in normal MAUI views. The issue only occurs when setting the font in a RemoteViews layout used for a notification.

Steps to Reproduce:
Create a RemoteViews layout with a TextView.

Set a custom font using SetTypeface or a font family reference.

Display the RemoteViews as an ongoing notification.

Expected Behavior:
The TextView in the notification should display the text using the specified custom font.

Actual Behavior:
The custom font is ignored and the default system font is used instead.
