An exclamation mark located just before a link turns the link into an image when rendering to CommonMark Markdown 1.2

When rendering to markdown/1.2 some text ending with an exclamation mark directly followed by a link, the exclamation mark is escaped but the link is still read back as an image.

Steps to reproduce:

1. Render the following xwiki/2.1 content to markdown/1.2:

   a![[Page]]

2. The output is

   a\![[Page]]

3. Parse it back as markdown/1.2

Expected: the text "a!" followed by a link to Page.
Actual: the text "a!" followed by an image of Page (the backslash escape doesn't prevent the image syntax from being recognized).
