Review comment:
In this function, "measuringElement" is what is being used, so that's
being created. The code above is just saying that sm.element and
sm.measuringElement won't be updated, because, you know, !sm.
But yes, if !sm, then it is leaking "span" elements. But I don't think !sm
lasts forever (and I probably didn't want to update this.measuringElementRef
because I wanted to allow sm to eventually be set, somehow). I choose
temporary leak over crash. I didn't debug enough to determine why !sm.
