Set height:100% on #dijitEditorBody in addition to <body>.
Note that usually #dijitEditorBody is actually the <div> inside the <body>.

Setting height:100% on the <div> fixes the Chrome problem where typing ctrl-A
and then some characters locks up the editor.   Doesn't seem to affect IE or FF.
The scrollbar still seems to work (showing up when the editor content overflows).

Fixes and refactorings for Editor on Firefox.

Fixes Editor_a11y.html regression test failure and removes firefox specific code branches:

- make FF use contentEditable (like other browsers) rather than designMode
- make FF use nested <div> inside of <body> (inside of <iframe>), just like other browsers
- expand tabbing helper code (both for tabbing/shift-tabbing into and out of the iframe) to run on all browsers, not just IE
- reduce the number of branches in focus(), so that Chrome and FF use same path

Fixes #10415, #17560.
Refs #11898.
