/*  In most contexts we use `overflow-wrap: anywhere` to ensure that we can wrap
	as much as needed on mobile (see
	src/test/rustdoc-gui/type-declaration-overflow.goml for an example of why
	this matters). The `anywhere` value means:

	"Soft wrap opportunities introduced by the word break are considered when
	 calculating min-content intrinsic sizes."

	https://developer.mozilla.org/en-US/docs/Web/CSS/overflow-wrap#values

	For table layouts, that becomes a problem: the browser tries to make each
	column as narrow as possible, and `overflow-wrap: anywhere` means it can do
	so by breaking words - even if some other column could be shrunk without
	breaking words! This shows up, for instance, in the `Structs` / `Modules` /
	`Functions` (etcetera) sections of a module page, and when a docblock
	contains a table.

	So, for table layouts, override the default with break-word, which does
	_not_ affect min-content intrinsic sizes.
