Re: [w3ctag/design-reviews] Invokers API (Issue #920)

 > Is there a way to detect that this feature exists?
 
 Checking if an element has an `invokeTargetElement` property could be used as a feature detection mechanism.

While this is possible it would be potentially superfluous, popovers already have a togglePopover() function for example. It has been considered that actions should have a corresponding JS API though but idk if it makes sense to have the two go hand in hand always.

 Auto is the missing value default for the invokeaction attribute. `toggle' is just an explicit token for said action in the details case.

 Apologies this is a mistake in the explainer.
