$feed_title in posts does not match content of title field in feed database

[tux93]

My use case is the following: I have subscribed to a feed but want to customize the title shown when new posts are sent.

To do this I tried to modify the 'title' field in the 'feed' database, but new posts are still sent with the title that was set when subscribing, my notification_template looks like this: New post from $feed_title:<br/>$link
