Lyrics extension oddity

Here’s a curious behaviour, and I can’t tell if it’s deliberate or unintended:

I add some music in a bar, and enter a lyric with an extension line.

I leave a rest and then add some more notes. When I add a note in the next bar, the extension line jumps to fill the bar.

And there we have it. Of course.
