Overflow covers up contents for single line code segments

It's kind of finicky. If you make a long line, it wraps, but as soon as you put PHP highlighting on it, it does the overflow, and removing the PHP highlighting still leaves the overflow.

Code without PHP highlighting

asd fasfd as adsf asdfasd f asd fasdfasd fasdfasfas fasasdf sdf sdfasdf asas fasd fasd fasd fsdfaf dlasd asdf asf asdasg asg asdgasdgadgasdg 

Code with PHP highlighting

asd fasfd as adsf asdfasd f asd fasdfasd fasdfasfas fasasdf sdf sdfasdf asas fasd fasd fasd fsdfaf dlasd asdf asf asdasg asg asdgasdgadgasdg

Sometimes removing the PHP highlighting will still leave it with an overflow.
