Multiform application popup form with caption "sticks" to cursor

Open up the above mentioned demo (TMS Web Project) using MacOS Chrome Version 106.0.5249.119 (Official Build) (x86_64). Using a right-handed mouse, do the following:

  1. Left click on "Click here to open the second form".
  2. Once open, drag the window by holding down a left-click on the top bar and drag the window. Then, whilst still dragging the window, also right click once at the same time. Then release the mouse.
  3. Left click anywhere on the form. If you now drag the mouse around you'll find that the popup form has become "stuck" to the cursor.
  4. The only way to close the form is to right-click again so the form stops following the cursor, then move

    the cursor over the "Close form" button, then left click twice.
  5. An alert message appears. After closing the alert message a TypeError is logged in the console. This error persists as long as the cursor continues to move in the browser.

The above mentioned issues do not exist when performing the same actions in Safari v15.6.1.

We added extra code to guard against this. This will be included in the next update.
