I want to remove certain css-elements from the feed.
I've noticed there is already an feature for exactly that, but for my understanding it only works if I parse the website and not for rss-feeds.

This is the feed:
http://stadt-bremerhaven.de/feed
And I want to remove the class aawp

I've also tried to manipulate the feed by myself and added display:none; to the aawp-class. But this entry will be removed from freshrss. Not exactly sure why.
This is my feed:
<div class="aawp" style="display:none;">
and the feed in freshrss:
<div data-sanitized-class="aawp">
Maybe there should be an option to not manipulate the feed.
