Contenteditable can't scroll in ios/android and difficult to get focus

I normally need to click twice to focus on the contenteditable div , and if my input was long enough ,there is no scroll bar showed up (it’s normal in safari). If wraped this div with ion-scroll, then it can’t get focus at all. That’s my div:

    <div contenteditable="true" data-tap-disabled="true" overflow-scroll="true" style="height:200px;overflow:scroll;background-color:red"></div>
