	resized, as per #17414.)

	FWIW, I was about to suggest such a feature myself, even though
	I never use EWW in non-80-column windows at all.

	For me, one of the uses would be redisplaying HTML documents
	after tweaking the renderer’s own code, especially where such
	documents are actually dynamic, and reloading them is bound to
	produce different results every time.

	Besides, this change looks like one step towards solving #17414.
