Shortcode ultimate and WordPress 4.5 are not compatible

I noticed that the tooltip seems to have stopped working in WP 4.5, but other shortcodes I have been using so far seem to be working.

There should be a tooltip on the first link in the first paragraph of:

The tooltip doesn’t appear here, and neither does it display correctly in the live preview. It does, however, faintly appear *underneath* the dialogue for the shortcode when hovering over the live preview.

Recent WP 4.5 core screwed up formatting in the WP Twenty Eleven theme and others and is in the process of repair/new version because of that – I believe 4.5.1 or 4.6 will be released around 4-28-16. I say this because the WP 4.5 issues may be affecting this and other plugins as well – I would update to new WP core as soon as it is released and check your plugin for proper function.
