Same for the height attribute. If you improve your trigonometry skills
when checking for the sun-position variable you can also add have a look
at this ;)

That would require the map rotation to be available as expression
variable (not sure if it is). Compensating for it with this variable
shouldn't be hard.

Can you file an issue?
