           Summary: Implement finishPropagation() method

          Severity: major
    Classification: Unclassified
                OS: Windows XP
          Reporter: jab_creations@yahoo.com
          Hardware: PC
            Status: NEW
           Version: unspecified
         Component: DOM

The DOM lacks the ability to finish executing events leaving authors having to
guess if an event has finished executing or not.

The need for the finishPropagation method can be summarized by the following
Gecko bug here...
https://bugzilla.mozilla.org/show_bug.cgi?id=768310

In short while working on a rich text editor I discovered that Gecko browsers
copy the (X)HTML code of a page selection. In the absence of the ability to
convert the selection to plain/text in older browsers I have the caret focused
on an invisible textarea where after the event finishes the selection is
automatically converted to plain/text. I then had to have JavaScript copy the
text and place it where the user expected the text to be copied to. At best I
had to use the setTimeout method under the presumption that x-number of
milliseconds should be sufficient.

By having the finishPropagation method I would instead be able to not guess if
an event has finished firing. This would free authors from having to rely on
setTimeout which should NOT have to be used so far out of context as
work-arounds.

It's very important that finishPropagation be implemented for ALL events both
triggered by users and those artificially created through document.createEvent.
