Description of Change
Fix issue disposing TabbedPage on iOS. For the compatibility handlers the
Element
is being accessed through a shim. The problem with doing this is that the shim nulls out theelement
before the dispose call happens. I realize that I could have reversed the calls inside the shim so dispose is called before the element is set to null but it seems really risky to change the ordering of things at this point. So, I instead went down a path of least change. I also applied this concept to a few other compatibility handlers we have.Issues Fixed
Fixes #10362
