Invoking callback functions
]]

I feel like we want this to be a <dfn> thing that we can cross-reference. That way it is more clear when a specification does not define what to do with a callback that throws.

Or we should have this as a lower-level hook and then a higher-level hook that is "invoke and report" as Ian just suggested on IRC. That higher-level hook should maybe be in HTML?
Comment 2 Ian 'Hixie' Hickson 2014-03-24 16:50:11 UTC 
Happy to add something that invokes a callback and then catches and reports exceptions. Assign this bug to me when "invoking callback functions" is ready, or file a new bug on me?

Note: bug 27046 added the "report the exception" algorithm which reports an exception to window.onerror.
Comment 4 Domenic Denicola 2016-06-02 20:49:16 UTC 
A plan for the exception-handling behavior was discussed in https://github.com/heycam/webidl/pull/113#issuecomment-218640902 and is tracked at https://github.com/whatwg/html/issues/958. The original request for a <dfn> was fixed in https://github.com/heycam/webidl/pull/113.
