The Problem

Popovers configured with slots (Title, Content, or both) can visually "break" (render incorrectly) when a user un-hovers and then quickly re-hovers an elementbefore the fadeout animation completes.

See:

This can be mitigated by setting theno-fade option totrue.

Steps to Reproduce

1. Position the mouse over an element configured with a popover, triggering the fade in.
2. Move the mouse off of the icon, triggering the fade out.
3. Quickly relocate the mouse over the popover information icon (before the fadeout animation completes).
