Hello,

the "clean formatting" button in the Editor deletes Text.

1. Create unorderd List with 3 entries and 3 indents like:

• Point 1
• Point 2
• Point 3
  • Point 1.1
  • Point 1.2
  • Point 1.3

2. select all the indent Points 1.1 to 1.3 and click the "clean formating" 

clean formatting is cleaning (deleting) the Points 1-3 :

After clean formating looks like this:

Point 1.1

Point 1.2

Point 1.3

It is reproducable on your Demosite

Regards

Michael Pospischil
