Thread:Extension talk:RSS/img tags not removed?

I am using the latest version of this Plugin and the latest stable version of MediaWiki. By default $wgRSSAllowImageTag is false, but when I include an RSS feed onto a Wiki page, image tags are still rendered, but they are displayed as plain text (presumably because I didn't configure MediaWiki to allow img tags?).

I simply want the img tags from the feed entry to be gone completely, is that now what $wgRSSAllowImageTag = false is supposed to do?

The weird thing is... when I leave $wgRSSAllowImageTag at its default value or set it to false manually, the amount of characters from the img tag counts towards the total characters of the feed entry (in regards to item-max-length).
