Wont suggest css classes unless you first make a space.

This is very strange.
In this case: <div class="myClass"></div> it wont work.
But in this case: <div class=" myClass"></div> it does work.

Notice the space before the class name in the second line.
What can be the problem?

I assume you are supposed to invoke suggestions with ctrlspace in this case (?)

This is the intended behavior. As @myfonj said you have to press CTRL+Space in order to trigger the suggestions. It's just how I thought it would make sense at the time I developed it, you can suggest a different behavior opening a new issue.
