Fail to track what revision made this test comes to crash on EFL port. Need to investigate why this test generates a crash.

Edje return the nullptr if the size of element is bigger than 20000 pixels.

Below comments are defined in isFormElementTooLargeToDisplay()[RenderThemeEfl.cpp].
    // This limit of 20000 pixels is hardcoded inside edje -- anything above this size
    // will be clipped. This value seems to be reasonable enough so that hardcoding it
    // here won't be a problem.

I think fast/overflow/overflow-height-float-not-removed-crash2 crash is normal.

Edje -> WebKit EFL port
