You don't ever set this value?  Did you forget to update it in
RenderViewImplAndroid::OnUpdateTopControlsState?

RenderViewImplAndroid::OnUpdateTopControlsState/UpdateTopControlsState where the
constraints are updated.

If the field is moved to RenderViewImplAndroid, this code should also move there
(you can call into it from this function).

Done.
