[Zotero 7 Beta] Problems with duplicate RSS Feeds

mjthoraval

If you try to add an RSS Feed that is already in your Feeds, Zotero will fail silently without any warning. So if you use a different name for the new feed from the one already in your Feeds, it looks like the addition was successful, but you cannot find anything under the name you have just typed.
It would be better to get an error window explaining what happened. At the moment, you can only see an error in the Debug Output:

[JavaScript Error: "Feed for URL already exists: https://www.annualreviews.org/action/showFeed?ui=45mu4&mi=3fndc3&ai=sv&jc=fluid&type=etoc&feed=atom" {file: "chrome://zotero/content/xpcom/data/feed.js" line: 257}]

If you make a tiny modification in the URL, still keeping it a valid URL for the RSS Feed, a new feed is created, but it is completely empty.
1) Add the RSS Feed from the URL: https://www.annualreviews.org/action/showFeed?ui=45mu4&mi=3fndc3&ai=sv&jc=fluid&type=etoc&feed=atom
2) Add the RSS Feed from the same URL in http instead of https: http://www.annualreviews.org/action/showFeed?ui=45mu4&mi=3fndc3&ai=sv&jc=fluid&type=etoc&feed=atom
-> The https feed is working while the http feed (added after) is empty.
Debug ID: D129222231
Zotero 7.0.0-beta.73+398454f85 (64-bit)
Windows 10

If you exchange 1 and 2, the http feed is working while the https feed is empty, showing that both feeds should be working.

Same for any variation of the URL, like feed=rss instead of feed=atom: https://www.annualreviews.org/action/showFeed?ui=45mu4&mi=3fndc3&ai=sv&jc=fluid&type=etoc&feed=rss
