### Reproduction
StackBlitz link: https://material.angular.io/components/autocomplete/examples#autocomplete-optgroup
I was not able to reproduce it at StackBlitz maybe it has something todo with the stucture and the scrolling areas of the page.
Steps to reproduce:
1. Open it on an device with an virtual keyboard
2. click in the autocomplete of "Option groups autocomplete" when its in the bottom part of the screen
### Expected Behavior
Expected to scroll the autocompletion entries whenever the autocompletion entries are visible.
### Actual Behavior
Actual the scrolling does not work as expected.

调研方向
从 StackBlitz 的 autocomplete optgroup 示例开始,在带有虚拟键盘的 Android Chrome 上,将 autocomplete 放置在屏幕底部附近并重现该问题。比较键盘可见时的滚动情况,并确定涉及的 component 或 overlay 入口点。当此位置的可见 autocomplete 条目能够正常滚动时,即表示完成。
