In Wiki or OUWiki, it's been discovered that adding styling to an existing link text may break a link to a page.
For example, in Wiki and OUWiki, this source text will create a link to a page "My Second Page":
[[My Second Page]]
e.g. My Second Page
If you select the visible link text and click "Bold" in Moodle's editor, the link could become broken.
This is because Moodle will have inserted "<strong>" tags around the text, like so:
[[<strong>My Second Page</strong>]]
e.g. My Second Page
At that point, because HTML tags separate the square brackets from the link text, it no longer looks like a link to the Wiki module.
Resolve this issue by simply removing any characters that separate [[ and ]] from their link text.
