Comment:

 What a mess. This resulted in #22175 (table attributes), #22790 (embed
 codes), #22842 (embed codes round 2). It seems TinyMCE does not conform to
 basic backwards compatibility principles and that's a major problem.

 We tried a duck punch in [23119] and [23120] to override TinyMCE's schema
 definitions, but it wasn't enough. The whole thing is systematically
 broken and it is simply not repairable without giving upstream some time
 to get things straight. The schemas are inconsistent and incompatible,
 embed code handling is entirely broken, and TinyMCE's media plugin seems
 to break horribly on the HTML5 schema.

 Very simply, we're throwing in the towel for 3.5 and will have no choice
 but to revisit in 3.6.
