I think I found the root cause of this bug: the PathView behaviour has
been changed in 5.4.x. Previously PathView was creating all the items in
the model, but now it behaves exactly as ListView, creating only the
visible items. Which in turn causes binding loop in the number of items
calculation, pathItemCount being the property which drives the amount to
be created. We calculate the item number based on the created item's
height, which in turn causes binding loop...
