AWB deletes closing </p> tags with general fixes turned on. In case of the opening tag containing some attributes, e.g. align="center", this style will apply to unwanted subsequent text until some closing tag that somehow survives.

What the hell? Not only deletion of the ending tags is unjustified in any case, also <center> is obsolete in HTML 5, so I don't get why there is even a discussion needed to get this fixed with invalid instructions for fixing our code.
Do you really think the only use of the <p> tag is centering?????? What the hell is this your 'fix' on fixing something that ain't broken? What is your problem with the way the <p> is used? Huh?
