Server OS version: OSX

Browser version: Chrome

Original install method (e.g. download page, yum, from source, etc.): master

**Describe the bug:While I was testing scatter plot visualizations and had my console window open, I happened to see this huge warning in the console - It said Can't call setState (or forceUpdate) on an unmounted component. This is a no-op, but it indicates a memory leak in your application
Full console warning captured here :

warning.js:33 Warning: Can't call setState (or forceUpdate) on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in the componentWillUnmount method.

It didn't hamper anything, but application memory leak warning is not good.

cc @elastic/kibana-sharing It seems you recently changed the Sharing dialog in all applications, which seem to sometimes throw the above issue. I added the :Sharing label here.

@Rasroh I am also unable to reproduce this, could you provide some additional information what buttons, etc. you are actually clicking when this happens, have you opened the "Share" menu beforehand?

@timroes I was able to reproduce. Open the share top nav. Open either share option, "Embed code" or "Permalinks". Mouse over the ? to open the tooltip. Press esc to close the popover.

Looks like the bug is in EuiToolTip. I will see if I can put a fix together.

Created elastic/eui#1163 to resolve the issue. I will close this issue once a version of EUI with the fix has been merged into Kibana
