Android Mouse takes several seconds before being recognized by flutter. #132866
Description
While working on flutter/engine#44724 I found that android "see's" hardware mice plugged in to an android device several seconds faster than flutter.
To reproduce launch platform_tests/scroll_overlay and plug in mouse then scroll. Observe android view scroll and flutter views not scroll. Wait 3-6 seconds while wiggling the mouse then attempt a second scroll and observe android and flutter views scrolling in sync.
