Tooltip not closing properly with custom animation if open() is called during exit transition.

User has sent Qt Support an example project where is a tool tip with enter and exit transitions.

Example has been attached.

Steps to reproduce:

• Hit the left button once. Tooltip apears.

• Wait until the the Tooltip begins to fade out.
• Hit the left button a second time before Tooltip has faded out completely.
• The now created second Tooltip never hides automatically.

• - In some cases pressing the right buttons which calls ToolTip.hide() resets the situation.
