Currently, this is only used by workspace_window_resizer. I'm guessing it's
going to be used by panel_window_resizer soon though to implement the necessary
behavior?

That was my thought based on your suggestion, but as I mentioned in the CL,
after trying that it's less obvious to me that we will want to share logic, so
I'm putting it back.
