Tooltip Trigger "Click" should support ESC key to close tooltip

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

Return (=mouse click) opens the tooltip but if the focus is moved to the next element the tooltip stays while a mouse click somewhere else closes the tooltip.

Expected Behavior 🤔

Pressing ESC should close the tooltip.
