Tooltip still visible and stuck when transitioning to previous page

[tuhlmann]

Describe the bug A clear and concise description of what the bug is.

We use react-md 5.1.3

In our app we use tooltips like this:

<HoverModeProvider defaultVisibleInTime={200}>
  <Tooltipped id="weight-low" dense tooltip="Can (Low Priority)">
    <div>...</div>
  </Tooltipped>
</HoverModeProvider>

The HoverModeProvider is part of the component. Displaying the tooltips works just as it should. The problem occurs when I leave the page while the tooltip is still visible- on a Mac I can for instance do this by triggering the "browser back" with "CMD+Left".

In this case the tooltip remains on the previous page or any page loaded afterwards and will not go away. The only way to get rid of it is to CMD+R reload the page.

To Reproduce Steps to reproduce the behavior:

• Trigger a react-md tooltip to become visible
• Press CMD+Left (or CTRL+Left I guess) to go back to the previous page
• => tooltip is still visible and won't go away.

Expected behavior A clear and concise description of what you expected to happen.

Have some way to make the tooltip disappear.
