RSS with space add additional blank output that brings to horizontal scroll

**Describe the bug**
Between 0.51.00 and 0.51.3, when RSS feed has been changed, the RSS add additional blank output that brings to horizontal scroll.

**_The post is about reading the RSS in an external RSS reader, not in the app itself_**

**Version**
0.51.3

**How did you install?**
Cloudron.io

**To Reproduce**
Add ChangeDetection.io generated RSS feed to an RSS reader. You can use other RSS reader with compact view and the RSS Reader don't show all the output.

**Expected behavior**
The generated RSS has to be with less space between (added) or (changed) and the text, so it can bee viewed in compact mode, not have to be scrolled. As in older versions.

**Screenshots**

You can see the red line above, it takes to much space, so the feed viewer go over the available space.

Part of the RSS output is interpreted in a box that has to be viewed with horizontal scroll.
