New Medium template?

This morning I have found an unpleasant change when reading medium stories (at least using Firefox). See

The capture is from this story.

As you can see, small grey-on-white font almost forces me to use reader view in Firefox, which in turn don’t let me use medium’s highlight and comment.

Instead of sending this post to medium I rather prefer to publish it and see if it’s happening to other people using other environments.

Did it happen to you, fellow reader?
