The [hide] tag doesn't work. Once you hide, the background color doesn't apply anymore.
[background=#000000][hide]Extra Padding[/hide]change background color[/background]

Tried the special characters but & nbsp; or & #160; or U+00A0 but is showing up as normal text instead of a non-breaking space.
[background=#000000]& nbsp; change background color & nbsp;[/background]
