WMA has x, instead of InputForm[x] and there are no quotes around "x" in StyleBox["x"]. What gives?

Also I see a duplicate set of quotes. I am wondering about the merits of having exhaustive tests that are wrong, versus having limited tests that are right with tests that are skipped that need to be worked on.

I am trying to get useful references from WMA. This is exactly what I get when I evaluate MakeBoxes[OutputForm[x]]//InputForm in the WMA CLI.

What I see is:

Note the extra backslashes. This is slightly different.

Seems like a regression here.
