| Following actions must not emit resize events: page load, dynamic content generation, and page scaling.<br/> |
| |
| The spec DOM Level 2 Events states that the resize event occurs when document view size (a.k.a layout size) is changed. Refer to http://www.w3.org/TR/DOM-Level-2-Events/events.html<br/> |
| However, showing/hiding scrollbars shouldn't be considered a layout size change. Refer to webkit.org/b/80242<br/> |
