Test book used: Accessibility Tests Mathematics, version 1.1.1

Summary

Tested using Thorium 1.8.0 on MacOS with Voice Over, Also have MathJax Display setting turned on. With MathJax turned off the MathML is displayed and spoken by Voice Over incorrectly so all tests would fail if MathJax is turned off. To turn on MathJax go to the Settings / Display / MathJax to check this checkbox.

Test ID Name Description Result Notes
mathml-010 Navigating block MathML with assistive technology and other technologies The test checks if block MathML works with assistive technology and related technologies. Pass This Tests Passes except we are unable to navigate the MathML. It reads the entire equation correctly but when you try to interact with the equation by following the instructions to press the VO key + Shift DownArrow nothing happens. Visually the Math equation looked correct.
mathml-020 Navigating inline MathML with assistive technology and other technologies The test checks if inline MathML works with assistive technology and related technologies. Pass This Tests Passes except we are unable to navigate the MathML. It reads the entire equation correctly but when you try to interact with the equation by following the instructions to press the VO key + Shift DownArrow nothing happens. Visually the Math equation looked correct.
math-image-030 Navigating Block Math images followed by Summary/Details with MathML The test checks if block MathML works with assistive technology and related technologies in a HTML Summary/Details as an option to get at the native MathML. Pass The Image and its alt text was displayed and read correctly. Expanding the details worked as expected and Voice over read the math correctly but again the same issues as above where we are unable to interact with the mathML directly.
math-image-040 Navigating Inline Math images followed by commented out MathML This test shows an inline math expression as an image with only alt-text describing the math equation. This is not ideal but if a publisher can not use raw mathML directly this is an option for reprocessing in the future. Pass Math equation was visually correct and Voice Over read the alt text of the inline image correctly. No commented MathML was spoken or displayed as expected.

Test results for Extended Descriptions
Test ID Name Description Result Notes
extdescription-010 Detection and Utilization of HTML Details and Summary elements Check if you can use HTML details and summary successfully and read the extended description contained in it. Fail The contents of the extended description did appear in the details and now the focus stays on the summary element and correctly informs the user that it is now expanded. Closing the details did keep the focus on the summary element as expected. However when I moved into this details and got to the table it informed me correctly this Table had 4 columns and 5 rows however moving through the table had Voice Over jumping all around the table and skipping some of the columns and rows. (This same issue was observed in Thorium 1.7.3)
extdescription-020 Technique for linking to a single extended description placed in a separate HTML file via text hyperlinks Check if activating the hyperlink placed under the image takes you to a separate HTML file with extended descriptions, and the back link there brings you back to the image. Pass The link does take you to the new page with the extended description. You are placed at the top of the page and the heading is read and you can navigate immediately through the extended description, which is what I would expect to happen. However clicking on the backlink had a small issue. You are taken back to the initial link to the extended description and this is read correctly and you can activate it again to get back to the extended description which is expected behavior. However, when you try to move off this link you can't and trying to exit from this link brings you back up one level and you must interact again with the content which brings you back to the top of the page where you must select the hidden "underscore underscore" to get back to the link where you can finally navigate past this link element.
