Toast in EuiGlobalToastList doesn't disappear until the focus leave

[bollinic]

I am creating a button to hide a toast from <EuiGlobalToastList>, I am using dismissToast to hide the toast.

The toast won't dissapear until I focus out because of
https://github.com/elastic/eui/blob/master/src/components/toast/global_toast_list.js#L237

I can understand pausing the timer onMousover but pausing with focus is blocking a common scenario like I want to close the toast with a specific button

[snide]

This is on purpose because of accessibility. #717
