Actual Results

Heading structure is found to be inappropriate on the page. The text "Users in this group" is coded as <h3> instead <h2> which does not match the visual hierarchy on the page. As a result, screen reader users found it difficult to understand the page's content structure.

Expected Results

The heading levels should be announced as per the visual hierarchy by screen reader to understand the page structure for their users.

Use heading levels as per specification such as <h1> should be followed by <h2>, <h3> and so on.
Even though this is required at WCAG 2.1 at Level AAA, it is recommended that the discussed issue be addressed as screen reader users rely on headings heavily to understand the page structure.

<h2> Users in this group </h2>

Currently there is no known workaround for this behavior. A workaround will be added here when available
