Fix the rotate-screen image on iOS Safari for maze levels

[jmkulwik]

Description

Previously, going to studio.code.org/hoc/1 and then studio.code.org/hoc/3 on an iOS device would cause the rotate image to display partly offscreen.

This applies the fix from a the same issue in the oceans HOC tutorial #32206

I just noticed that this causes both fixViewportForSmallScreens_ and fixViewportForSpecificWidthForSmallScreens_ to be called, with the latter having the final word. Ideally, only one of these should be called. For example, in the case of /s/oceans, only the latter is called.
