Testcase

When a combination of block, inline and inline-block elements uses :hover styles, some of these :hover styles leave artifacts after mouse moves away.

In the attached testcase, the orange box displays two smaller boxes on hover. If you move your mouse away from the orange box, it should be rendered without any traces of the smaller boxes. This is not the case, parts of the inline element box (white) are still visible.

Reproducible in:
