6.5.3 Modern - iOS - safe-area-inset-bottom NOT WORK!

[[email protected]]

Hi all,
on ExtJs 6.5.3 Modern with cordova 8.0.0, platform iOS 4.5.4,constant(safe-area-inset-bottom) or env(safe-area-inset-bottom)
dont'work!
Instead safe-area-inset-top works!

html, body {
    background-color: yellow;
    padding: constant(safe-area-inset-top) constant(safe-area-inset-right) constant(safe-area-inset-bottom) constant(safe-area-inset-left);
    /* iOS 11.2 */
    padding: env(safe-area-inset-top) env(safe-area-inset-right) env(safe-area-inset-bottom) env(safe-area-inset-left);
}

Any idea?
No problem with same project on 6.2.3.

Thanks
