Validation error: "Error: Attribute slidesjs-index not allowed on element img at this point" appears on slideshow when checking with Microsoft Accessibility Insights tool #917
"Error: Attribute slidesjs-index not allowed on element img at this point." appears when validating with Microsoft Accessibility Insights.
Note that this error ONLY shows when you check with Microsoft Accessibility Insights. If you just go to https://validator.w3.org/nu/ and add the URL, you won't see this error.
This is likely because the tool uses a special process to check the serialized DOM as opposed to just the page source, so it is (granted) a more accurate version of what users will be navigating.
