See [1] for more context, but the idea is that instead of using just the DOM structure to establish the popover hierarchy, the user's behavior should matter. For example, if one popover contains a popover invoker pointing to another popover, it should matter whether that invoker is *actually used* to open the second popover. An example: - Component 1 is a third party widget, which uses popover - Component 2 is another third party widget, also using popover - A page wants to use both components separately, from separate invoking buttons. - Component 1 also wants to be able to use Component 2, via a button within Component 1. In this example, the page should be able to still independently use these components. So a user clicking the page's button for Component 2 is expected to close Component 1 if it's open, because that's a direct invocation of Component 2. However, if the user clicks the button within Component 1 to get Component 2, it is natural to leave Component 1 open because this is a nested call. Important note: this often happens to be the behavior even before this CL, since the user clicking on the page-level Component 2 invoking button represents a light dismiss signal for Component 1, so it closes either way. But this CL simplifies the implementation considerably, removing the need to track all invokers on the page, and also removing the need to continuously check whether invoker relationships have changed.

See [1] for more context, but the idea is that instead of using just

behavior should matter. For example, if one popover contains a popover

In this example, the page should be able to still independently use
these components. So a user clicking the page's button for Component 2
is expected to close Component 1 if it's open, because that's a direct
