Set how the tooltip should act if it is about to overflow out of the timeline.<br/>
Choose from <code>'cap'</code> and <code>'flip'</code>. <br/>
If it is set to <code>'cap'</code>, the tooltip will just cap its position to inside to timeline. <br/>
While if it is set to <code>'flip'</code>, the position of the tooltip will flip around the cursor so that a corner is at the cursor, and the rest of it is visible. <br/>
