does this really change the chapter ordering? you're reversing the way you parse all the elements, but then you reverse the whole chapter list again, so doesn't it end up being the same? do you have an example manga that has incorrect ordering with the old version but is fixed with this version?

why was the formatting here changed? it was better before

clippy would complain about it when testing in my repository, so fix that.

This is not true, it is done because of the special structure of the chapter list in this web page, which was overlooked by the previous people who implemented this source.
It can be confirmed by checking the web page on PC: https://www.manhuagui.com/comic/28004/
