Is there a reason not to just remove these two lines?

@scottgonzalez, technically, this would break with an alternate box-sizing. Should just be updated to .css('width') and .css('height') if anything.

Hi @kenjiyamamoto, thanks again for contributing this patch. We recently re-enabled the test suite for resizable. In order for us to land this patch, we'd need a few tests added to the test suite proving this doesn't break existing functionality and also that it fixes the bug as described. Can you add some tests here please?

I'm going to go ahead and close this pull request, as it's not a high priority to fix at the moment, and we'd need an active from response from @kenjiyamamoto to move forward, which have not gotten. @kenjiyamamoto, if at any point you'd like to continue pursuing this pull request, please submit a new one. Thanks again for the work here!
