<description>
Adds a meta tag to the tag stack. Similar to the BBCode [code skip-lint][url=something]{text}[/url][/code], but supports non-[String] metadata types.
If [member meta_underlined] is [code]true[/code], meta tags display an underline. This behavior can be customized with [param underline_mode].
[b]Note:[/b] Meta tags do nothing by default when clicked. To assign behavior when clicked, connect [signal meta_clicked] to a function that is called when the meta tag is clicked.
