Add Original Font Size in Rich Text

As it stands, using the rich text editor if you change your font size to anything other than the original (like what I'm writing with right now), you can't use the font size changer to go back to the original. 3 is too small and 4 is too big. I assume the original is ~3.5 but idk. Can we get that fixed? Thanks.

Example:

You MUST PM me... o shit wtf why is this so small how do I go back to original is this it? no..

Obviously this can be solved by simply switching to BB code editor but as it stands, not with rich text.
