Moving the mouse can cause absolutely positioned elements to move around #39439
Description
Describe the bug:
- Load the following HTML:
<!DOCTYPE html>
<div style="overflow: scroll; width: 150px; height: 150px; outline: solid;">
<div id=target style="position: absolute; background: green; width: 50px; height: 50px">hi</div>
</div>- Move the mouse outside and inside the Servo window.
- Observe that the absolutely positioned
<div>moves around. The<div>s offsets keep increasing in the flow tree output.
Curiously, reloading prevents this bug from happening.
