Description
This PR adds an Accessibility section to the CSS Custom Highlight API page.
Summarizes the intended behavior from the specification: the type attribute can be used by user agents to expose semantic meaning (such as spelling or grammar errors) to assistive technologies.
Notes that current support is limited and inconsistent across browsers and platform accessibility APIs.
Provides guidance for developers: custom highlights should not be relied on alone to convey important information; semantic HTML elements like
<mark>or additional accessible cues should be used when highlighting conveys meaning.This update ensures that developers are aware of accessibility limitations and helps prevent assumptions about screen reader support.
Fixes #43408
