Coding area - *Scroll down bar bug*

Tell us what’s happening:
Hi there guys,

I do not need any help, however I thought it might be good to post this (if not yet done already, if already please @mods just delete this post).

There is something wrong with the scrollbar in the coding area. When you use the scroll down bar with the mouse it doesn’t go all the way down until the last line of text. To get there you have to go down within the coding box itself and press the arrow to get down.

This is definitely a bug as the other scrolling bars are working perfectly fine as it seems so far.
