Mobile Safari - Input caret does not scroll along with overflow-scrolling: touch

Question

I know that Mobile Safari won't fire events while in "momentum" (-webkit-overflow-scrolling: touch;) scrolling. But this is not entirely the same thing, because Safari handles the (blinking) caret of an input internally.

<div id="container">
    <input type="text" />
    <div class="filling"></div>
</div>

#container {
    position: absolute;
    top: 20px;
    bottom: 20px;
    width: 50%;
    -webkit-overflow-scrolling: touch;
    overflow-y: auto;
    border: 1px solid black;
}

input {
    margin-top: 60vh;
}

.filling {
    height: 200vh;
}

Try this fiddle on your device (focus the input and then scroll): https://jsfiddle.net/gabrielmaldi/n5pgedzv

The issue also happens when you keep your finger pressed (i.e. not only when giving it momentum and releasing): the caret fails to scroll.

Obviously I don't want to turn off overflow scrolling, if there's no way to fix the caret so it will scroll correctly, it would be OK to hide it.

Thanks

This is indeed a WebKit bug and there seems to be no known workaround.
