[kb1m8s] Failed example 5 passes the rule due to role conflict resolution

[dd8]

Failed example 5 specifies a global ARIA attribute and role=none which triggers presentational role conflict.

	<h1 role="none" aria-brailleroledescription="Banana text">I like bananas</h1>

The expectation is

The test target is not prohibited for the semantic role of the element on which it is specified.

The h1 element is included in the accessibility tree due to the global ARIA attribute, and the semantic role resolves to role=heading, the implicit role of h1.

aria-brailleroledescription is not prohibited on the semantic role heading.
