When you hover over the "Share" button with the mouse, a tooltip appears that tells the user they can copy the link. After clicking on the button, a tooltip tells the user that the action was successful. These tooltips should also be visible on keyboard focus.

Acceptance Criteria

• Open a property page
• TAB over to the "Share" button.
• On keyboard focus, the "Copy link" tooltip should be visible.
• Press ENTER to activate the button.
• The "Link copied" tooltip should be visible.
