Show tooltip on disabled elements and disable tooltip

By default, tooltips will not be displayed on disabled elements. However, you can enable this behavior by using the following steps:

  1. Add a disabled element like the button element into a div whose display style is set to inline-block.
  2. Set the pointer event as none for the disabled element (button) through CSS.
  3. Initialize the tooltip for outer div element that holds the disabled button element.
