ADA Compliance issue bv-focusable

[apooler25]

Hello, we are trying to make our site ADA compliant and there are parts of your module that are rendered outside of Magento2 that are throwing compliance errors. When using a scanning tool the following issues arise.

Issue: Aria-disabled used where it is not needed and could conflict.
Selector: button[disabled=""][aria-disabled="true"][tabindex="-1"][class="bv-content-btn bv-content-search-btn bv-focusable"][type="button"]

When a role that is not valid is used on the button element the role may not be communicated to users of assistive technology or an incorrect role may be communicated that is not supported by the button element causing confusion for users of assistive technology.
Issue: Only specific roles can be used on the button element. See attached image roles are used on button and span within button.
Selector: span[role="option"][class="bv-dropdown-title"][id="bv-dropdown-title-reviews"
