Earlier this could be used to put some text centered on the line:
\startframedtext[middle][frame=off,background=]
\type{ABCDE}\crlf
\type{ABCDE}
\stopframedtext
Now, the "middle" doesn't seem to have any effect, the contents is put to the left side of the printing area.
Has there been a change in behaviour of \startframedtext or has a bug crept in?
