Yup, valid bug. The error is that, if an inline element is the last thing in a single-line shrinkwrapped container, when you position the inline its static position is instead computed as if it linewrapped onto a second line. Here's a testcase: <!DOCTYPE html> <div id=wrapper> <div id=inline></div><div id=inline-positioned></div> </div> <div id=cover></div> <style> body { margin: 0; } #wrapper { float: left; } #inline { display: inline-block; width: 50px; height: 20px; background: green; } #inline-positioned { display: inline-block; width: 50px; height: 20px; background: red; position: absolute; } #cover { position: absolute; top: 0; left: 50px; width: 50px; height: 20px; background: green; } </style>

If you move the <style> stuff above the first <div> there will be no red box seen. Your test case exposes another bug , that for positioned objects the renderers are not properly re-attached.

Here's the reduction without any collapsing space. It passes. data:text/html,<!DOCTYPE html><style>body { margin: 0; }#wrapper {float: left;}#inline {display: inline-block;width: 50px;height: 20px;background: green;}#inline-positioned {display: inline-block;width: 50px;height: 20px;background: red;position: absolute;}#cover {position: absolute;top: 0;left: 50px;width: 50px;height: 20px;background: green;}</style><div id=wrapper><div id=inline></div><div id=inline-positioned></div></div><div id=cover></div> So this the same issue as bug 45274.
