Update fragment link event listener selector to exclude links inside WYSIWYG editors

This MR fixes a bug in core/misc/form.js which causes browsers to navigate to an anchor when a user clicks on a fragment link within a WYSIWYG editor. See related issue for details.

How to test this PR

1. Create a new node of a content type that uses a WYSIWYG editor.
2. Scroll down to the editor.
3. Create a link within the WYSIWYG editor that points to #main-content.
4. Click on the link.
5. Observe that the browser does not jump up to the top of the page.

Closes #3339741
