Bug 243190 – css column-count nesting with position absolute has wrong offset parent at nesting level 3 and greater

• Status: NEW
• Component: CSS

nested divs with column-count >= 2 and absolute positioning has incorrect layout at third level and lower. It looks like the third level and subsequent levels get set to positioning from document not offset parent.


	<div style="position:absolute; top : 50px;left:50px; border : 1px solid red;column-count:2;background-color : white">
		<div>level1</div>
		<div>level1</div>
		<div style="position:absolute; top : 50px;left:50px; border : 1px solid red;column-count:2;background-color : white">
			<div>level2</div>
			<div>level2</div>
			<div style="position:absolute; top : 50px;left:50px; border : 1px solid red;column-count:2;background-color : white">
				<div>level3</div>
				<div>level3</div>
			</div>
		</div>
	</div>
