THIS TEMPLATE IS FOR FILING BUGS ON THE ANDROID SYSTEM WEBVIEW. GENERAL WEB
BUGS SHOULD BE FILED USING A DIFFERENT TEMPLATE!

Device name:samsung galaxy tab 2
Android version:5.1.1
WebView version (from system settings -> Apps -> Android System WebView):56.0.2924.23
Application:app I'm developing
Application version:

URLs (if applicable):



Steps to reproduce:
(1) create an element, such as a div,with a fixed height and overflowing content.
(2) apply following css:

div
{
   overflow:auto;
}

::-webkit-scrollbar {
    -webkit-appearance: none;
}

::-webkit-scrollbar:vertical {
    width: 12px;
}

::-webkit-scrollbar:horizontal {
    height: 12px;
}

::-webkit-scrollbar-thumb {
    background-color: rgba(0, 0, 0, .5);
    border-radius: 10px;
    border: 2px solid #ffffff;
}

::-webkit-scrollbar-track {
    border-radius: 10px;  
    background-color: #ffffff; 
}

::-webkit-scrollbar-thumb:window-inactive
{
    background: rgba(255,0,0,0.4);
}

Expected result:scrollbars should appear, just as they did in older versions of webview.


Actual result: No scrollbars appear
