Editing Ribbon Button Icons Are Scrambled

[ZeldaTheSwordsman]

Several of the button icons on the editing ribbon are shuffled around from where they should be.

As shown in the picture, "Quote" has what I assume is either the "Spoiler" or "Preview" icon. The other errors are as follows:

• "Spoiler" has the icon for "Align Center"
• "Insert/Remove Bulleted List" has the Numbered List icon
• "Insert/Remove Numbered List" has a T-with-subscripted-x icon.
• "Align Center" has the "Align Right" icon
• "Align Right" has the Bulleted List icon.
• "Preview" has the "Quote" icon.

The heck is going on?
