[False Positive] aria-hidden-focus on elements with data-tabster-dummy

[ultrababs]

Describe the bug

There is a known issue with Fluent where they use Tabster which uses hidden focusable elements. These elements cause numerous false positives for aria-hidden-focus on WCP accessibility scans. There have been quite a few open tickets about this over the years. Is there any possibility of hiding this false positive from WCP scans to prevent failures going forward?
