Bold wiki link with an anchor or a query string located in a table cell breaks the table in CommonMark Markdown 1.2

Render the following xwiki/2.1 content to markdown/1.2 and parse the result back:

|x|**[[label>>Space.Page||anchor="t"]]**|d

Expected: the same table, with a bold link in the second cell.
Actual: the cell is split. In a table cell, a pipe located inside bold (or italic) content ends the formatting, and the separators of the wiki link reference parameters can't be escaped since the wiki link parser splits on the first pipe.
