[csswg-drafts] [css-fonts] font-stretch, user agents "may" swap range endpoints?

tabatkins has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-fonts] font-stretch, user agents "may" swap range endpoints? ==
In the [font-stretch descriptor](https://drafts.csswg.org/css-fonts-4/#font-prop-desc), it says that:

> User agents may swap the computed value of the startpoint and endpoint of the range
> in order to forbid decreasing ranges.

I'm pretty sure this is an incorrect use of "may".  The spec probably means this to be a "must", phrased something like:

> If the startpoint of the range is greater than the endpoint, user agents must swap the startpoint and endpoint for the computed value.
