    Is that really that mysterious? Just seems they went out of their way for clickbaity title.

      That's correct. The original paper doesn't call it mysterious, just "unusual". Science PR people are under a lot of stress to get pageviews.

        The original description was most likely “hmmm… that’s funny”.

      The mysterious (unpredicted/as yet unexplained) aspect is the precise physics of its emission properties. It's a refinement of known physics sure, but that doesn't make it less interesting. Not unlike how finally completing a full physics accounting for how bicycles remain upright would be fascinating even if positively pedestrian.
