ngHide/ng-show directive don't animate in ng 1.4.4

[e-cloud]

when i update to angular 1.4.4, there is a strange thing -- some animation i define for the element with ng-hide directive doesn't seem to work. Then i check the api docs. Ok, the 1.4.4 version docs of ng-show's example plunkr seems to have no animation too.

Does Angular have enough tests before the new version is about to release?

Can you please provide a demo of the problem? Otherwise, we cannot do anything to fix the problem.

Just look how work original example or plunker
when check labels angular don't add intermediates classes:

.ng-hide-add
.ng-hide-add-active,
.ng-hide-remove
.ng-hide-remove-active

I think that problems related with #12612, #12583

Ok, I see now. @matsko can you take a look at this? It seems pretty bad if even the "official" ng-hide animations aren't working.

Turns out that the API docs example code is incorrect. Transitions always need to be applied to the non active CSS class:

Or on the class that is being added or removed:

Or on a shared CSS class that is always there:

Placing it on the active CSS classes may have worked before, however it was never intended. But not to worry, I will look into making the fix properly for 1.4.5. Here is an issue to keep note of that:
#12638

In the meantime here is a commit that will clean up the example in the docs a bit so nobody else comes across this issue:
#12637

Sorry I provided the wrong link earlier. Here is a patched version of angular.js that fixes the issue: http://plnkr.co/edit/YLTe1SObEAaQn99iOiNv?p=preview

This patch will debut in 1.4.5
