Remove redundant `autoscroll_horizontally` during editor prepaint (#34218)

* Experimentally `scroll_manager.anchor()` appears to be the same before
and after this 2nd call of `autoscroll_horizontally`

* Nothing these depend on seem to be mutated between the calls (and
since this is prepaint, stuff within editor also shouldn't be mutated)

Release Notes:

- N/A
