AbbreviationInlineRendererRenders a Markdig Markdig.Extensions.Abbreviations.AbbreviationInline as a Avalonia.Controls.TextBlock inside an Avalonia.Controls.Documents.InlineUIContainer with a tooltip showing the full definition.
CodeInlineRendererRenders a Markdig Markdig.Syntax.Inlines.CodeInline as a styled Avalonia.Controls.Documents.Run. Using Run (instead of Border+InlineUIContainer) keeps the text selectable. In right-to-left text, the code is wrapped in a left-to-right isolate (see MarkView.Avalonia.Rendering.Inlines.DirectionIsolate), so it reads left to right in one piece.
FootnoteLinkRendererRenders a Markdig Markdig.Extensions.Footnotes.FootnoteLink inline as a clickable superscript reference. Clicking navigates to the footnote definition anchor (fn-N). Back-links are skipped.
HtmlInlineRendererRenders a Markdig Markdig.Syntax.Inlines.HtmlInline. Recognizes common self-closing tags (e.g. <br>, <br/>) and renders them as their visual equivalent. Other HTML tags are silently ignored.
LinkInlineRendererRenders a Markdig Markdig.Syntax.Inlines.LinkInline as a MarkdownHyperlink span or image. YouTube video links (produced by UseMediaLinks) are rendered as clickable thumbnails. An image that cannot be loaded is replaced by a markdown-image-failed placeholder. With IsLazyRenderingEnabled, an image not cached yet starts loading once it nears the viewport. While IsProvisional(MarkdownObject) holds for a link or image (its address may still be growing), a link keeps its text, class and title but gets no NavigateUri, and an image (a YouTube one included) is written as its alt text in a plain Avalonia.Controls.Documents.Run, nothing being loaded.
LiteralInlineRendererRenders a Markdig Markdig.Syntax.Inlines.LiteralInline as an Avalonia Avalonia.Controls.Documents.Run.
SmartyPantInlineRendererRenders a Markdig Markdig.Extensions.SmartyPants.SmartyPant (Markdig's UseSmartyPants()) as the typographic character it stands for: curly quotes, en and em dashes, ellipsis and guillemets.
TaskListRendererRenders a Markdig Markdig.Extensions.TaskLists.TaskList outside a list item as an inline check glyph.
