fix(tooltip): Fix md-tooltip showing when window receives focus
When the parent of an md-tooltip was clicked, it received focus. When the window was blurred and re-focused (e.g. on tab change), the tooltip shows again due to a new focus event firing. This fix prevents this first focus event from having any effect. Note that this bug only affected browsers that focus buttons on click. Fixes #3035. Closes #4191.
