And now I know the reason of the described problem:
createBitmapContextFromWebView in EFL port is using ecore_evas_buffer_pixels_get() to get the content of the pixel test result.

>From ecore_evas_buffer_pixels_get() documentation at http://docs.enlightenment.org/auto/ecore/group__Ecore__Evas__Group.html:

"Besides returning a pointer to the actual pixel array of the given canvas, this call will force a rendering update on ee, first"

So EFL DRT invalidates the view itself when generating pixel test result.
