Markdown hyperlink references break on single-word page names

[joemiller-soapbox]

When using markdown to add page references to pages with a single-word title, the links break. For example, a link of the style:
[some text here]([[Page]])
Renders as
%5B%5BPage%5D%5D
in the garden.

Oddly enough, it works when the text exactly matches the page name, and it works when the page name is more than one word. IOW, both this:
[Page]([[Page]])
and this
[some text here]([[Page Name Here]])
work just fine.

The bug is case-sensitive, as well.
[page]([[Page]])
also renders as
%5B%5BPage%5D%5D
