However, if the ‘transition-property’ property changes such that the transition would not have started, the transition must stop (and the property must immediately change to its final value).

The question is whether, if the end-user's cursor passes over an element, activating "hover" (setting display to "block") and then exits (because there was not intent to interact) within the 500ms before the transition begins, setting display back to "none", would cause the end value of display to be "none" or "block".

In https://hg.csswg.org/drafts/rev/b6e5bb6bf803 I've clarified that
this includes the delay phase.  (The prose in question has also
since become non-normative, with more formal wording defining the
behavior.)
