fix(aio): correctly process markdown link in "Browser Support" (#18349)

The markdown processor expects an empty line between an opening tag and the
markdown content. (If there is no empty line, the content is interpreted as
plain HTML.)
Previously, the line between the opening `<td>` and the content contained
whitespace, which caused the content to be interpreted as HTML and not markdown.

Fixes #18312
