Unnecessary scrollbars in compilation errors area

[lydell]

Notice how there are disabled scrollbars in the right-hand area where the compilation errors are. This is because the area has overflow: scroll; (which always shows scrollbars) rather than overflow: auto; (which only shows scrollbars if needed).

This looks like Firefox but what OS on you on? I've seen these appear on user's devices before, I wonder if it's related to some system setting. I'm not able to recreate this on OS X in any browser.

This particular screenshot is from Ubuntu, but it happens on Windows as well, regardless of browser.

On mac, you need to connect an external mouse or set General > Show scroll bars: always.

On my mac, I usually use the always setting to avoid making the overflow: scroll; mistake myself :)
