Issue: Vaultwiki custom BBcode not allowing BBcode toggle to work - XenForo 2.2

Hello,

The VaultWiki "Wiki Attachment Tag" custom bbcode, found in VW 2.1.8, when activated, will not allow the bbcode setting to be changed. This is the bbcode setting enabled by the brackets [ ] in a new or reply to post window, on the upper right side, in XenForo.

Disabling this specific custom bbcode, allows the bbcode toggle [ ] to work again. I tried each custom VaultWiki bbcode individually (enabling and disabling) and this was the only one that broke the XF bbcode toggling function. This is repeatable.

It does not throw any error codes in XenForo's admin control panel.

Thought you should know, for the next revision.
