To anyone interested in tracking this behavior, here's what I can say for now.

Filling list in the given example changes from tag 'release_8.0.7' to tag 'release_8.1'.

I keep you updated. Have a nice day,

Whoops! I swore when I tested that it filled the lists, but you're
right! Hmm. Just sent a follow-up to the list clarifying that this did
*not* work, as well as including a link where it turns out I actually
asked the same thing some 2 years ago! Hope someone chimes in to help
you out. I definitely would like to use something like this, as when I
edit lists in my work reports/presentations, I mess up the nicely
filled original wrapping behavior and I'd like to tidy it back up.
