bug#51398: 29.0.50; Rcirc displaying wrong order on messages

[Benjamín Buccianti]

On messages with the same hour and minutes, it shows recent ones 
previous to older ones, when it should be the opposite.   Example: 
17:37 <technomancy> everyone should be taught applescript in 
school
17:37 <technomancy> so that we can be sure not to repeat the 
terrible mistakes of history
17:37 *** roto JOIN
17:37 *** TOPIC Current stable is 27.2 | "If that's Emacs, I love it. If not, I 
cannot wait to unpack that with ya." -- Ted Lasso | EmacsConf 2021 CFP now open!

Those technomancy messages wasn't there when I entered #emacs on libera,
also take a look at how my JOIN show after, it doesn't makes sense.
