Timeout of zero causes Pause on hover to close toast

[jtwotimes]

Also found on the demo site:
For any of the toast types except Prompt, if the timeout is 0 and Pause on Hover is on, mousing over the toast and then mousing out of the toast causes the toast to close. This issue no longer happens if Pause on Hover is off. I would expect the Pause on Hover to have no effect on the toast when the timeout value is set to zero since there is no progress bar.
