When I serialize a HTML document including elements with ARIA related attributes, serialize method drops them off as a result of sanitization.

import html5lib
doc = '<div id="foo">the description</div><span aria-describedby="foo">bar</span>'
print(html5lib.serialize(html5lib.parseFragment(doc),
                         sanitize=True, quote_attr_values='always'))
# <div id="foo">the description</div><span>bar</span>

ARIA related attributes are not dangerous for my understanding, so serialize method should keep them even if the parameter sanitize is True.

The text was updated successfully, but these errors were encountered:
