Please update to 15.3.10 that we have just released and this will be fixed.
Just a note, though: If you install and build the new version you will see that when the object is destroyed during an async event, the CSS rule will be also removed from the style sheet. The underlying IW JavaScript code also removes the empty <style> tag. However the browser refuses to remove it from the style sheet collections of the DOM of the current page, so you might end up with some empty style sheets, which have no undesirable side effects
