Forum Image align="left or right" interferes with Post Signatures in 4.0.6
 

I've been trying to construct a custom BBCode specifically for using text wrapping. It works well in both the Blog and CMS but when used in forum posts it upsets the post signature.

align="left" and align="right" both cause signature interference whereas align="top", align="centre" and align="bottom" don't interfere with the post signature.
I need align="left" to work in posts properly. For some reason it doesn't.

My BBCode allows images to be posted at a reduced size and enlarged using double-click, reduced again using single-click, and with text wrapping.

BBCode:

Demo Posted Here of posted BBCode that works using multiple lines of text.

However when using no added text or between 1 to 10 lines of added text the image interferes with the posted signature.

align="left" using no added text extends down in to the signature area and pushes it over:

align="left" using one line of added text extends down in to the signature area and pushes it over:

align="left" using multiple lines of text works fine:

Has anyone got any clues why align="left or right" don't work in 4.0.6 posts? The align issue is not isolated to images. The problems also extends to tables using align="left or right". Any help would be appreciated thanks.
