Regression test for issue #54477.

Browse Source 
I removed the original file that more completely captured the original
crate's tests, as its source crate
(https://crates.io/crates/collection) is licensed under GPL3, and I
suspect that license is not loose enough for me to put into our repo
under our MIT/Apache licensing.

(Would it be an option to attach the GPL3 licesne to just the one
test? Probably. But do I want to bother with it that that point?
Nope!)
