App keeps fetching new copies of the same posts from giantitp.com on each refresh

[kazerniel]

Describe the bug Each time Fluent Reader checks for updates of this feed (either automatically or manually), it fetches the 10 newest posts with the timestamp showing as "now". This is a site that only updates once every few months, so it's essentially the same 10 posts repeating as many times I press refresh, always as if they were published "now".

To Reproduce Steps to reproduce the behavior:

1. Add https://www.giantitp.com/comics/oots.rss to Fluent Reader
2. Click on Refresh a few times
3. See error

Expected behavior For it to only fetch new posts if they are actually new.

Platform (please complete the following information):

• OS: Win 10.0.19045
• Version 1.1.3

Additional context Other RSS readers don't seem to have this issue with that feed, that's why I suspect it's something about the app rather than the feed.

I'm experiencing the same problem with the following feed: https://www.volkskrant.nl/economie/rss.xml

There's one specific article - https://www.volkskrant.nl/kijkverder/v/2023/met-de-zee-vloeit-het-zout-de-mekongdelta-in-en-verdwijnt-de-rijst~v910518/ - that keeps getting fetched and marked as new, filling up my feed with duplicates of the same article.

OS: Fedora 38
