            find={true}
            onFindQueryChange={this._findItem}
          />
    </div>
  </Panel>

Expected / Desired Behavior / Question

When I use this code directly (without an panel) it works corrently.

If I embed the toolbar inside of an panel, the filter does not work and sometimes I got the following error message in my browser:
Blocked aria-hidden on a element because the element that just received focus must not be hidden from assistive technology users. Avoid using aria-hidden on a focused element or its ancestor. Consider using the inert attribute instead, which will also prevent focus. For more details, see the aria-hidden section of the WAI-ARIA specification at https://w3c.github.io/aria/#aria-hidden.

How can I fix that?

Observed Behavior

Filter opened and chooseable

Steps to Reproduce

• Add an toolbar inside of an fluent ui panel

Thank you for submitting your first issue to this project.

I have reproduced your scenario. It turns out that filter popup does in fact open and render properly, but it is placed below the panel due to lower z-index value (popup control has z-index: 1000, whereas panel has z-index: 1000000).

You would see the popup if you had changed z-index to a value higher than panel has:

As a quick fix, I would recommend changing your code and switching Panel from fluentui to Dialog from fluentui/react-northstar. Dialog component has z-index: 1000 and works well with nested popups. https://fluentsite.z22.web.core.windows.net/0.66.2/prototype-nested-popups-and-dialogs
