Mathtype integration interferes with other double-click handling

[bendemboski]

Description

I have experienced this in the CKEditor5 plugin, but I believe it applies to all integrations. Because of this line, other double-click handlers installed after the Mathtype integration's double-click handler or higher in the DOM will not work.

In my case, I have another unrelated feature that tries to listen for double-clicks and when the mathtype plugin is enabled, that feature doesn't work.

Environment

Which version of MathType does this happen in? @wiris/mathtype-html-integration-devkit@1.17.5

What is the relevant software and their versions?

• Editor (CKEditor, Froala, TinyMCE, etc.) CKEditor5 44.0.0
• Framework (Angular, React, etc.)
• Browser (Chrome, Firefox, etc.) all
• Operating System (Windows, macOS, Ubuntu, etc.) all

Steps to reproduce

Write code that adds a dblclick handler to the editor root after the integration has installed its handler, or that adds a dblclick handler to a higher-in-the-DOM element. Double-click inside the editor.

Expected result

The handler is called

Actual result

The handler is not called

I wonder if #1059 will remove the need for that problematic stopImmediatePropagation() line of code because it prevents the double-event registration?
