Resizable: Remove bad workaround for draggable+resizable

jzaefferer · jzaefferer · commit 3576ceb360eb · 2014-04-16T18:47:15.000+02:00
This adds a compound test page for draggable+resizable, which had no coverage before. Using that page shows that there is no way to reproduce the behaviour described in the original ticket that caused this workaround, since its not possible to resize an element beyond the window boundaries. Therefore removing the workaround, which is 6+ years old and has no test coverage, seems like the sanest approach. Fixes #6939 Closes gh-1210
