Upgrading our compose version from 1.1.beta03 to current and one of our unit tests for a Popup started hanging.
I can see in the history in beta04 a change was made adding a loop in popup I'm not sure how to workaround.

We hang in the unit test asserting there is a popup:
```composeTestRule.onNodeWithTag("ActionView").assert(hasAnyAncestor(isPopup()))```
I can see in the callstack that AndroidPopup is hung here:
```    LaunchedEffect(popupLayout) {
        while (isActive) {
            awaitFrame()
            popupLayout.pollForLocationOnScreenChange()
        }
    }```
in new code that was added in this change: <https://github.com/androidx/androidx/commit/d78c06d7d95724b6fe19f03128ae633c9796a9f6#diff-1528b749e18fe9e9996a5f677bf21aebaffb524612e3270795610b144c55a8b2|https://github.com/androidx/androidx/commit/d78c06d7d95724b6fe19f03128ae633c9796a9f6#diff-1528b749e18fe9e9996a5f677[…]fb524612e3270795610b144c55a8b2>

I looked into this some more creating a simple test project, we use robolectric for our tests where this hangs, in a non-headless environment the hang doesn't happen
