"TypeError: Cannot read property 'focus' of undefined" when using md-tabs #8111
Description
Issue #6776 has been abruptly closed (and discussion restricted) four days ago with a comment about a bug in Angular 1.5.4 due to a change which was being reverted. However, the original report used Angular 1.5.0, so it's hardly believable that the culprit could be a change that was not even made at that time.
Others in that thread reported the problem was not present in 1.5.3. But I recently had to downgrade to Angular 1.4.8 in order to have that TypeError disappear.
Specifically, it had to do with md-tabs. I was unable to had tabs shown in the most simple document while working with a bunch of combinations involving Angular 1.5.4, 1.5.5, 1.5.3, and Angular Material 1.1.0rc3. I maintain that md-tabs do not work correctly with any 1.5.x version of Angular. Also, on the Angular Material website, the Angular version used on the demos page is... guess what? 1.4.8. How convenient.
