Syntax [[...]] in terminal page breaks rendering and indexing of content

So the root cause of this bug is that this content is parsed by the relative entity reference parser and the relative entity reference parser returns null for empty references.

[], [.] and [..] are working because they are special keywords interpreted as ("current document", "current space" and "parent space"). But ... is just a regular reference which means <missing space>.<missing space>.<missing document>, but in the case of a "relative" resolve we don't missing pieces.
