Textareas seem to be able to overflow (and are in some cases)

@ Luke.Leber, I have checked this issue in my local. I can't able to see any text area over flows in revision log message.also text area's max-width is 100%.

I'm also unable to reproduce this, so at least steps are needed to reproduce this as by default a max-width of 100% is set.

This was 100% self inflicted by a module hijacking the textarea template! Sorry for the noise.
