Google Chrome 32 follows the specification and click on interactive elements in <label> doesn't activate the labeled element.

For UA requirements, the spec says "The activation behavior of a elements that create hyperlinks is to run the following steps: ..." http://www.whatwg.org/specs/web-apps/current-work/multipage/text-level-semantics.html#the-a-element a without href doesn't create a hyperlink, so doesn't have an activation behavior defined, so the "run synthetic click activation steps" do not apply. 99615 2 tkent 2014-02-03 14:05:08 +0000 Ah, Simon is right. I overlooked "The activation behavior of a label element for" in [1]. [1] http://www.whatwg.org/specs/web-apps/current-work/multipage/forms.html#the-label-element > The activation behavior of a label element for events targeted at interactive content descendants of a label element, and any descendants of those interactive content descendants, must be to do nothing.
