Do not apply viewport attributes and contents size during page transition as this affects user interaction
The contents size is only applied in PageViewportController::didRenderFrame, the initial scale as well, so that only leaves minimum/maximum scale and user scalability.
Closing this bug because the EFL port has been removed from trunk. If you feel this bug applies to a different upstream WebKit port and was closed in error, please either update the title and reopen the bug, or leave a comment to request this.
