Title:
  improve the implementation of selection resizing

Status in webbrowser-app package in Ubuntu:
  Confirmed
Status in webbrowser-app package in Ubuntu RTM:
  Confirmed

Bug description:
  (see also bug #1122145 that should be fixed as a prerequisite)

  The selection functionality in the browser allows the user to resize the selection rectangle by dragging one of the four handles to include additional blocks.
  The current implementation is rather naïve, it computes the center of the resized selection, gets the DOM element below this point, and iterates up the DOM tree until it finds the largest ancestor that fits in the selection rectangle.

  This is hopefully good enough for the demo (considering the tight
  deadline), but it should be made smarter afterwards.

  This bug report should be used to gather ideas on how to make the
  feature smarter, and track their implementation.
