MarkdownStyle is being overridden in constructor

[rzinnatullin]

There is MarkdownStyle property in MarkdownScrollViewer control.
It can be set directly, or via a style.
However, setting it via a style does not work, because its value is being overridden by Standard Markdown style:

        public MarkdownScrollViewer()
        {
            Engine = new Markdown();
            SetCurrentValue(MarkdownStyleNameProperty, nameof(MdStyle.Standard));
        }

The overriding is happening in MarkdownStyleNameProperty change handler (UpdateStyleName method):

owner.MarkdownStyle = (Style)prop.GetValue(null);

Please fix the issue.

To workaround the issue I've created a descendant class and added the MarkdownStyleFixed property which I set in a style:

    public class MarkdownViewer : MarkdownScrollViewer
    {
        public static readonly DependencyProperty MarkdownStyleFixedProperty =
            DependencyProperty.Register(
                nameof(MarkdownStyleFixed),
                typeof(Style),
                typeof(MarkdownViewer),
                new PropertyMetadata(null, UpdateMarkdownStyleFixed));

        public Style? MarkdownStyleFixed
        {
            get => (Style)GetValue(MarkdownStyleFixedProperty);
            set => SetValue(MarkdownStyleFixedProperty, value);
        }

        private static void UpdateMarkdownStyleFixed(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            var control = (MarkdownScrollViewer)d;
            control.MarkdownStyle = (Style)e.NewValue;
        }

        public override void EndInit()
        {
            base.EndInit();
            if (MarkdownStyleFixed != null && MarkdownStyleFixed != MarkdownStyle)
            {
                MarkdownStyle = MarkdownStyleFixed;
            }
        }
    }

Hope this helps to someone until the original issue is fixed.

I released v1.15.
Setting a value to MarkdownStyleName in constructor is removed.
