Wierd Emmet autocompletion problem

[alexbet]

I am having weird Emmet auto-completion problem now. Let say I want to expand a div with a class like this:

.slider

And I hit Tab to expand to <div class="slider>. It was working before, but now instead of the HTML expanding, all classes that contain the word "slider" cycle after the dot in .slider and it never expands. This is very frustrating as this is a very simple expansion, and now it is not working any more.

Any suggestions how to fix this?
