@shunguoy unable to validate, test files do not exist in branch dev-1304:
test/v2/checker/accessibility/rules/aria_semantics_role_ruleunit/summary_element.html
test/v2/checker/accessibility/rules/aria_semantics_role_ruleunit/li_element.html

Validated aria_semantics_role
Rule aria_hidden_nontabbable aka aria_hidden_focus_misuse does not have a failed test case. Hold in push

[shunguoy]

@ErickRenteria the test case is correct. This PR fixes a false positive that shows up in the original one (first screenshot) and has a “The ARIA role ‘button’ is not valid for the element

“, once it's fixed (second screenshot), the error is gone. No need for a failure case.

The test/v2/checker/accessibility/rules/aria_semantics_role_ruleunit/summary_element.html contains the test for the aria_hidden_nontabbable and aria_hidden_focus_misuse cases though not in the rule test folder.
