missing Keyframe css for animations if @tailwind base is missing
Just upgraded to 1.6.0 and the animation css is generated but not the matching keyframe css - this is for the default animations and any custom ones I create.  This is the case with a blank config file.  

I have used everything else fine with no @tailwind base; instead using my own smaller reset css.
