Colons are parsed incorrectly in bitbucket comment system

When you upload an image or post a link in a comment/issue/etc that has a colon in the name it fails to be displayed.

The src value is left out from the img tag. The image does successfully upload as can be seen here: https://bitbucket.org/repo/LboRq/images/3594091313-sample:.png

If I try to title the link the same thing happens. This doesn't occur for links with ports.
