Hi Team,

The rendered PanelBar automatically generates:

<ul role="tree">
    <li role="treeitem" aria-expanded="true">

These sections are not a hierarchical tree; they are used as accordion-like form sections. Due to the incorrect tree/treeitem roles, the screen reader is not able to identify and announce these sections correctly, which can cause confusing navigation for users relying on assistive technologies.

Please consider updating the role of the PanelBar to be an accordian instead of a tree.

Thank you!
