Jordan Hofker 76c5726c04 Check before calling blur on activeElement.
It's possible for slides to be in a situation where the last clicked thing was an SVG before the tab/window loses focus. When returning, `.blur()` is called on the previously-active element, but can result in an exception.

This protects against that and will only call `.blur()` when `document.activeElement` supports it.
