In a ctool modal form for Panels inside IPE Panels, submitting the panel form allows you to leave the page w/o an ajax pop-up

We have the very specific case that we edit our panels within IPE Panels using ctool modal forms.
Which means that when we create a panel, we still have to save the layout page to confirm the changes.

I noticed that when I created a panel without saving the layout page, I could leave the page however i wanted without the Ajax pop-up

Do you want to leave this site?
Changes you made may not be saved.

This is because in the onUserExit.js file all forms submits will call the function
userMovingWithinSite();

I added an extra check, to see if the form is not part of a modal form.
