The toolbar.destroy() call that was added in 5c38995bd9 was
needed to destroy the dummy toolbar when tearing down VE
before a surface had been intialized. But when tearing down
VE after the surface had been initialized (e.g. exiting using
the Read tab), we would do:
* setTimeout in tearDownToolbar()
** Set toolbar height to 0 and wait for transitionend
*** toolbar.destroy() once transition complete
* toolbar.destroy() in cancel()
This meant that we'd listen for a transitionend event
on an unattached element (because once the setTimeout runs,
the toolbar has already been destroyed by the second call),
which of course never fires, so we'd never resolve the
tearDownToolbar deferred and never finish tearing down VE.

VisualEditor provides a visual editor for wiki pages. It is written in
JavaScript and runs in a web browser.
It uses the Parsoid parser to convert wikitext documents to annotated HTML
which the VisualEditor is able to load, modify and emit back to Parsoid at
which point it is converted back into wikitext.
For more information about these projects, check out the VisualEditor
and Parsoid pages on mediawiki.
For information about running tests and contributing code to VisualEditor,
see CONTRIBUTING.md. Patch submissions are reviewed and managed with
Gerrit. There is also API documentation available for the
VisualEditor.
