Is this intentional? And, if it is, is there a way to re-supply the missing bar line?

Yes, and yes. This is a frequent question, so I've wondered a couple times if we should come up with a new command to recommend instead of \bar, but it's not clear that the alternatives are better.

https://gitlab.com/lilypond/lilypond/-/issues/6414 is related.

In short, from LilyPond's point of view, the bar line at the end of the previous system is the same bar line as the one at the start of the new system. Which is not illogical, considering that they would be the same if there were no line break.

Consequently, the \bar command defines *both* bar lines. And if you look at the list of bar lines at https://lilypond.org/doc/v2.24/Documentation/notation/list-of-bar-lines , you can see that \bar ".|:" has no drawing at end of line. \bar ".|:-|" does.

With that being said, you probably don't want to use \bar in the first place. Just use \repeat volta, or if that's not feasible for whatever reason, repeatCommands.
