[Tracking] AIWeb skips unresponsive iframes

Describe the bug

Our extension makes a best-effort attempt to scan child iframes - we send messages to the child frame and wait for a small timeout. If the child frame does not respond by our timeout, we skip the child iframe. This is a tracking issue for cases when the extension skips child iframes unexpectedly.

If you are running into this issue, please comment below with the following information:

• Steps to reproduce the behavior
• A target site URL or code pen repro example
• OS Name & Version (e.g. Windows 10.0.18363 Build 18363 / macOS Catalina 10.15(19A583))
• AI-Web Version & Environment (e.g. 1.140.1 Insider)
• Browser Version (e.g. Google Chrome 78.0.3904.108 (Official Build) (64-bit))
• [Optional] Screenshots, additional context

Context

The purpose of this issue is to track all known instances of AI web skipping iframes unexpectedly. It is pointed to in the iframe skipped warning banner, added in https://github.com/microsoft/accessibility-insights-web/pull/6330

This has started to show up as an issue when testing components within our Storybook site for Microsoft Graph Toolkit.

Load this url: https://mgt.dev/?path=/story/components-mgt-agenda--simple Wait for the page to load and then run a FastPass scan.

OS: Windows 11 Enterprise Version: 22H2 Build: 22621.1702

AI-Web Version: 2.38.1

Browser: Microsoft Edge for Business Version 114.0.1823.30 (Official build) beta (64-bit)

Is there any known work arounds I could look into?

Hi, @gavinbarron! We've looked into this, and StoryBook's IFrames can't be scanned by Accessibility Insights for Web. StoryBook is sort of an artificial hosting environment, so we don't recommend it as a test bed for assessing the accessibility of your controls. You'll get a much more meaningful result by hosting your control in a simple test page and scanning that page using Accessibility Insights for Web.

As an alternative, StoryBook has an accessibility add-on that is intended to provide accessibility testing within StoryBook. This add-on is based on axe-core (the same engine used by Accessibility Insights for Web), but because it uses a 2020 version of axe-core, its results may be somewhat behind current WCAG standards.

Thanks for using Accessibility Insights!
