on-set-size-constraint (augments, and augmentable only) in mode:host-text-mixin

Called before the editor's maximum or minimum height or width is changed, after can-set-size-constraint? is called to verify that the change is ok. The after-set-size-constraint method is guaranteed to be called after the change has completed.

(This callback method is provided because setting an editor's maximum width may cause lines to be re-flowed with soft carriage returns.)

  If a surrogate is set, calls the surrogate with the arguments it was passed, plus this and a function that calls the super method.

  if a surrogate is not set, calls the super method and returns that result.
