I'm sure it's semi-intentional....pretty sure it's grammatically
incorrect for a title to end in a period.
MLA citations require book titles to be in title case followed by a
period.
Since you can control it by selecting or not selecting the
punctuation, I'd call it a feature myself.
OTOH, article titles need to be in title case followed by a period, but
set within quotation marks - Word *DOES* toggle Title case when the text
is within quotes - IF you don't include *BOTH* quotes in the selection
(selecting either the beginning or the ending quote will toggle title
case but not sentence case, selecting both will toggle sentence case but
not title case). That's just a wee bit too fine grained for me, thank
you very much.
My evaluation: It's a bug, in the sense of a feature gone awry.
Especially since there's nothing in Help to assist one in making sense
of the vagaries.
If one definition of insanity is to do the same thing over and over, but
expect a different result, then doing the same thing over and over and
actually getting a different result must be the precursor.
Think how much code must have gone into that "feature" just to eliminate
one case (which the user may in fact want), and which the user could
bypass by a single key tap.
