/* if selection change includes the web page (either as 'from' or 'to' node)

* - to detect when navigation should leave the IE history and use MMC history navigation
* - to ensure we always leave IE only after navigating to a pagebreak - to stop the
* scripts on the page as soon as we hide it. to achieve that we need pagebreaks
* before every web page and after every web page.
*
* to do so we need one of the following:
*
* 1. Add a pagebreak (used when selection changes from the web page to non-web view)
* 2. Add a pagebreak and navigate
* (a. when selection changes from web page to another web page)
* (b. when selection changes from non-web view to the webpage
* and it is the first web page in the history)
* 3. Navigate only. ( when selection changes from non-web view to the
* webpage [except #2.b case] - pagebreak had to be added when leaving the
* previous web page)
*
* inverting the said will result in:
* - add a pagebreak if :
* C1: web page is a 'from' node (#1. and #2.a.)
* C2: web page is a 'to' node
* && no previous web pages
* && 'from' node is a non-web view (#2.b)
* - navigate to web page if:
* C3: "to' node is the web page
