Bug 199659 – AX: VoiceOver ignored role="presentation" on <table> HTML elements

• Status: RESOLVED
• Resolution: FIXED
• Component: Accessibility

[chris fleizach]

VoiceOver ignored role="presentation" for HTML table elements.

1. View the following markup in Safari with VoiceOver.
<button>hello</button>
<table role="presentation">
<tbody role="presentation">
<tr role="presentation">
<td role="presentation">Some text</td>
<td role="presentation">Paragraph</td>
</TR>
</TBODY>
</table>
2. Navigate to the text node named "some text"
3. VoiceOver announces "Table start". It should not do this because role="presentation" means that assistive technologies should ignore the native semantics of the element. This is a simplified example from https://www.w3.org/TR/2017/WD-wai-aria-practices-1.1-20170628/examples/presentation/PresentationRoleExamples.html

the reason why <table role="presentation"> is used here instead of a simple <div> is because of support for really old browsers with limited CSS capabilities. Hence, <TABLE> elements are used for styling.

This is a regression since IOS 11.0. Can be reproduced on up to IOS 12.3.1.
