* Introduced preliminary idea for infinite recurse exception
* Better handling of infinite recursion
But it could be better still...
* the TransclusionError is a proper error
Moved the magic number to be on the error's class. Not sure if that's
a great idea.
* Fixed minor minor issue that came up in conflict
The minor fix to the jasmine regexp that escaped a '+' somehow
broke some random test.
* Removing patch fix for recursion errors
* Fixed issue where buttton and other widgets don't clean up
* Added release notes for #9548
* Update test-widget.js
If I don't fix those indentations, the entire TW codebase will explode or soemthing.
* Update test-widget.js
These lint problems are wasting my time.
* Fixed all core widgets to not leak when renderChildren fails
* Updated release notes to reflect what I'm actually fixing
* Update test-widget.js
Added warning not to use for-of loop for defining tests. The iterating variable needs to have its own method scope, or it risks being the same value for all tests.
Getting rid of the old widget mechanism files finally gives us a payoff
for all the refactoring. Still a bit of tidying up to do, and we need
to re-introduce the animation mechanisms.
