Question: Minor Bug in typesetting extended for mathbackground?

In regards to executing a command to output text in color I have stumbled across a minor bug?

Tools -> options -> display -> typsetting level : Extended

Typsetting[Settings](autoatomic) #checking default autoatomic setting (don't know if this really matters though)
                 true

Type in    testing    - select the word then Format -> Character -> Highlight Color ... (choose green for example)
select word and right click  2D Math -> Convert to -> Atomic Identifier

The word should be highlighted green, then press enter for maple to display the ouput.  It is not highlighted

lprint(%)
                  `#mi("testing",mathbackground = "lime")`

Even though output is not displayed highlighted green, it is coded that it is.  However if we highlight the output code and ... Format -> Character -> Highlight Color...  it shows the highlighted color it should be.  But here's the added twist, if I cancel that operation VOILA! Lo and behold - all of a sudden the displayed output is highlighted green (that's odd)

However, if we had Typsetting level set to Maple Standard it is fine.  Did I miss something or is that a bug in the extended mode?
