Edge: addMouseWheelListener and addMouseListener have no effect

[rubenporras]

Describe the bug
When using an Edge browser, if the methods addMouseWheelListener or addMouseListener are used, the listener is registered but never executed.

To Reproduce

    Browser browser = new Browser(browserContainer, SWT.NONE);

    browser.addMouseWheelListener(e -> {
      System.out.println(e.toString());
    });
    browser.addMouseListener(new MouseListener() {

      @Override
      public void mouseUp(final MouseEvent e) {
        System.out.println(e.toString());
      }

      @Override
      public void mouseDown(final MouseEvent e) {
        System.out.println(e.toString());
      }

      @Override
      public void mouseDoubleClick(final MouseEvent e) {
        System.out.println(e.toString());
      }
    });

Expected behavior
The listeners are called when the scroll wheel is used or the buttons of the mouse is are clicked inside the Edge window

Environment:

1. Select the platform(s) on which the behavior is seen:

• • [] All OS
• • Windows
• • Linux
• • macOS

Workaround (or) Additional context

Use the SWT.IE when creating the browser.
Use a javascript function to react to the scroll wheel / buttons and register a normal BrowserFunction as a callback.

Related to (possibly a duplicate even):

• Edge: Implement mouse-related event listener support #2097
• Add MouseEnter & MouseMove Event in PopupCloser eclipse.platform.ui#2977
• Registering MouseEnter and MouseMove Events in PopupCloser eclipse.platform.ui#2996

@rubenporras would you like to continue the discussion in some of those? Also, the description of the issue seems wrong, you wrote "if the methods addMouseListener or addMouseListener are used," (same method twice)

Thanks, I have fixed the title and description of the ticket

[rubenporras]

From the related PRs, I think that #2097 would fix the problem I am reporting.
