Broken icon on 4.0.2 -> v5.0.0-a0* update
## About this issue

Hello! Facing an issue on `4.0.2 -> v5.0.0-a0*` update.
Using an icon in a simple `ImageView/AppCompatImageView` works just fine, but an attempt to use this same icon in `com.google.android.material.bottomnavigation.BottomNavigationView` via programmatic menu:

```
    mainBottomNavigationView.menu.apply {
      add(
        Menu.NONE,
        R.id.feed_nav_graph,
        Menu.NONE,
        R.string.title_feed
      ).icon = IconicsDrawable(
        requireContext(),
        MaterialDesignDx.Icon.gmf_border_all
      ) //gmf_border_all is not working
    }
```
Results in some sort of invalid icon:

**4.0.2:**
