Cannot shift-tab out of editor on IE

[simonjb]

To reproduce:

• open /dijit/tests/test_Editor.html
• tab to editor text
• press shift-tab to focus the toolbar
• press shift-tab

Expected:

• focus to go to the first thing before the editor (the IE application toolbar)

Actual:

• focus returns to the editor text

Notes:

• only happens on the first editor on test_Editor.html
• only happens when you go from the editor to the toolbar; ie. tab to first toolbar and shift-tab works fine
• possibly related to ​http://trac.dojotoolkit.org/changeset/12148 See ​http://archive.dojotoolkit.org/dojo-2008-01-24/dojotoolkit/dijit/tests/test_Editor.html and ​http://archive.dojotoolkit.org/dojo-2008-01-25/dojotoolkit/dijit/tests/test_Editor.html

I am not making much progress on thie ticket. I am putting it on hold until the new editor is landed as I suspect the problem may be related to the iframe. If the editor overhaul doesn't appear by Feb 25 I will tackle this again as it needs to be fixed for 1.1.

(In [12842]) Fixes #4996, #5835 !strict. IE wanted badly to focus the iframe's BODY tag on the way in and out. I added an onfocus handler for IE that just moved the focus either up or down another level to avoid stopping on the BODY tag. Also fixed a few code-style issues. becka11y verified correct behavior.
