Created attachment 438036 [details] Reduced testcase When an element has display:inline in a parent with writing-mode:vertical-rl, the offsetLeft property of the element is calculated incorrectly. In some cases, a negative number may be returned. This behavior can be observed in the attached test case, which prints the value of offsetLeft to the console.
