Created attachment 479205 [details] Minimal reproducible example Steps to reproduce: 1. Open attachment. 2. Try to drag resize handle. Expected behavior: The element resizes. (Works in Chrome and Firefox.) Actual behavior: The element does not resize. From what I can observe, the following circumstances are necessary for this to occur. - The iframe has a resizable parent. - The parent's resize handle overlaps the box of the iframe.
