Describe the bug:

When using the flyout to review a document in Discover and making use of any of the action buttons (filter in, filter out, etc...) the hover menu persists until clicking somewhere else in the page. If you don't click and the hover on another button then the new hover menu is overlaid the previous hover menu. Additionally, if you scroll then the hover menu persists as well in a portion of the flyout menu that may or may not be relevant for that section.

Steps to reproduce:

1. Perform a search in Discover
2. Open the flytout in Discover view for a document
3. Click any action button and then scroll and/or hover on another action button
4. Observe the previous hover menu persists

Expected behavior:
I would expect the hover menu to disappear when no longer engaged with it (i.e. having my mouse hovering the area)

Screenshots (if relevant):

Hover menu on top of another hover menu:

Hover menu in space when scrolling away:

Errors in browser console (if relevant):

None

Provide logs and/or server output (if relevant):
n/a

The EUI team proposed a UX solution where we prevent two tooltips being present in the DOM. If a user toggles a tooltip, we should check for any tooltips present, close them, then reveal the new tooltip.
