labelSpans property
The label, already parsed and styled with style.
The parse has happened by the time a builder runs, in the
MarkdownScope.linkLabel scope, so [**bold** link](url) arrives as the
spans that render it. An autolink's label is one plain run, deliberately:
re-parsing a URL would let ItalicMd eat the underscores out of
https://example.com/a_b_c.
Implementation
final List<InlineSpan> labelSpans;
