Summary of inconsistent ACT rules below.

• Failed examples should be failed by at least one of the Checker rules.
• Checker should be mapping (report against) the same success criteria as what is expected by the ACT rule.

1. Partial: Element marked as decorative is not exposed 46ca7f

   • Mapping: The Checker implementation reports different success criteria as failed from what is expected by this rule. Checker reports 1.1.1 while ACT expects None.
   • aria_attribute_valid: Pass, Fail_invalid_role_attr, Fail_invalid_implicit_role_attr
   • img_alt_null: potential_aria_override
   • "failed by " aria_attribute_valid on Failed Example 1

2. Partial: Image has non-empty accessible name 23a2a8. Checker reports

   • "inapplicable" Failed Example 2
   • "passed" Failed Example 5

3. Partial: Scrollable content can be reached with sequential focus navigation 0ssw9k

   • Mapping: ACT is incorrectly expecting mapping to a AAA 2.4.3 Keyboard (No exception). Checker doesn't support AAA's

4. Partial: Meta element has no refresh delay (no exception) bisz58

   • "passed" Failed Example 2
   • "passed" Failed Example 3
   • Mapping: Checker reports against 2.2.1 Timing Adjustable, while ACT expects both 2.2.4 Interruptions and 3.2.5 Change on Request.

5. Partial: Orientation of the page is not restricted using CSS transforms b33eff

   • "inapplicable" Failed Example 4
