In Environment -> Headers, it's possible to define and save completely empty headers :
Later, when executing a request there's a warning regarding the empty header, and only a thin gray line to show it (as it's inherited and not editable, it's almost invisible) :
It would be interesting to make the empty header more visible (I had to search were it was to understand the warning) and/or to warn when saving an empty header in environment settings.
