[HTML5] stage.stageHeight includes tab bar height on iPhone safari

[HTML5] stage.stageHeight includes tab bar height on iPhone safari

Fixed with hackish way:

//on iPhone safari, tabBar height is not excluded from window.innerHeight
        #if html5
        untyped __js__("
            function getH()
            {
                const topBar = document.getElementById('topBarContainer')
                let topOffset = topBar ? (window.innerHeight - Number(getComputedStyle(topBar).height.slice(0, -2))) / window.innerHeight : 1

                function getComputedStyle(node) {
                    return node.nodeType === 1 ? node.ownerDocument.defaultView.getComputedStyle(node, null) : {};
                }

                return window.innerHeight - topOffset;
            }
        ");
        #end

        var height:Float = #if html5 untyped getH() #else stage.stageHeight #end;

May be there is a nicer workaround?

I believe stage.stageHeight is based upon the size of the parent DIV element on the site, so perhaps there is a way to change the CSS of the index HTML page so that it shrinks below the top bar?
