        // In some cases, app can have specific Window for Android UI components such as EditText.

        // In this case, Window bounds != App bounds. Hence, instead of ensuring non-negative

        // PopupWindow coords, app bounds should be used to limit the coords. For instance,

        //  ____  <- |

        // |   |     |W1 & App bounds

        // |___|    |

        // |W2 |    | W2 has smaller bounds and contain EditText where PopupWindow will be opened.

        // ----  <-|

        // Here, we'll open PopupWindow upwards, but as PopupWindow is anchored based on W2, it

        // will have negative Y coords. This negative Y is safe to use because it's still within app

        // bounds. However, if it gets out of app bounds, we should clamp it to 0.
