There is a web accessibility issue in the cookie banner that causes an "ARIA attributes do not match their roles" validation error.

Problem: The elements that function as tabs (like the "Declaration" section) are implemented with role="button". However, they also use the aria-selected="true" attribute, which is not valid for the button role. This negatively impacts screen reader users.

Example Code (Incorrect):

<div role="button" id="cookiescript_declaration" aria-selected="true" ...>

Solution: Please change the ARIA role of these elements from role="button" to role="tab". The tab role is semantically correct for this component and fully supports the aria-selected attribute, which would resolve the accessibility error.

Example Code (Correct):

<div role="tab" id="cookiescript_declaration" aria-selected="true" ...>

This is a crucial fix for WCAG compliance and for making the banner accessible to all users. Thank you!
