fix(renderer): remove unecessary setElementStyles method

There is no need to expose this additional method inside of the Renderer
API. The functionality can be restored by looping and calling
`setElementStyle` instead.

Note that this change is changing code that was was introduced after
the last release therefore this fix is not a breaking change.

Closes #9000
Closes #9009
