There is space beneath teaser images in some situations

Problem

The .teaser--stream selector is not more specific than the .teaser selector. In some situations this causes the styles for .teaser to be applied last. This can break the height for stream teasers causing visual issues with images.

Solution

Change the selector to .teaser.teaser--stream so that it's more specific and styles are properly applied.

This should happen for both the default style as well as the sky flavour.
