Reddit GIF Files are not loaded in Feed View

[rom-1]

Hi, I am using FeedMe with FreshRSS. I disabled all Download Options, as I do not need Offline Sync. This means if I go to a RSS post, the content is showing up in real time, not from a downloaded cache. This works great with .jpg images and video files (mp4). But .gif files are never displayed.

Example
This is the original link fetched by RSS: https://www.reddit.com/r/memes/comments/mo44sj/just_like_the_simulations_hopefully/
In FreshRSS, this is the content of the post, and also this is the content that is fetched by FeedMe:

<div class="text">
  <div class="reddit-image figure">
       <img src="https://i.redd.it/tnvhc360fcs61.gif" class="reddit-image">
  </div>
  <div>
  submitted by   <a href="https://www.reddit.com/user/EpicWizard123"> /u/EpicWizard123 </a>   to   <a 
  href="https://www.reddit.com/r/memes/"> r/memes </a> <br> <span><a href="https://i.redd.it/tnvhc360fcs61.gif">[link] 
  </a></span>   <span><a href="https://www.reddit.com/r/memes/comments/mo44sj/just_like_the_simulations_hopefully/"> 
  [comments]</a></span>
  </div>
</div>

So, the gif source url is: https://i.redd.it/tnvhc360fcs61.gif
This gif shows fine in FreshRSS Web Interface.

When looking at the FeedMe overview post list, this seem to work, there is a small thumbnail visible, screenshot:

When viewing the post content, the GIF does not show up:

After going back to the FeedMe overview post list, the thumbnail has suddenly disappeared:

I already tried fiddling with the feed settings, and clearing the cache multiple times, but I don't get it to work. When trying to switch to "web" view, it says: "this page is too large, size: 3147068 byte".

These are my feed settings: https://user-images.githubusercontent.com/37835829/114296372-6173db80-9aab-11eb-8ff8-5acd09374a9d.jpg

@rom-1 can you pls provide the rss url here or via mail?

@seazon I can provide the rss url, but this will not help you. This is the rss url: https://www.reddit.com/top.rss but it contains a lot of content, not only gif files. maybe you have better luck with this one: https://www.reddit.com/r/gifs/top.rss or https://www.reddit.com/r/gifs/new.rss
