Further investigating: the difference lies in the title and what you
finally get. If you're left with a single word, then you get a simple text.
If you have any space, then it's a link.
thus the following code
<$set name="last" filter="[{!!title}removeprefix[jingle ]]"><<last>></$set>
will produce a "bells" simple text in the "jingle bells" tiddler BUT a
"bells song" link in a "jingle bells song" tiddler.
