BUG FIX: Ticket #4217

BUG FIX: Ticket #4217


Hello,
I reported a bug concerning "resizable" interaction when
"containment:parent" is activated. (cf.:Ticket #4217). I worked on an
issue and I propose a solution to solve it. The bug fix is explained
in the Ticket.
I worked too on an other Ticket #3053. I think it is related to #3719
and #3732. (The problem appears when "ghost" option is enabled). I
found the issue and I corrected it. (explainations are contained in
the Ticket 3053)
I hope you will take it in account and commit this issue fix. (4
tickets could be closed by comming this two little fix).
Best regards.
