Affects Version/s: 7.0.X, 7.1.X, Master
CKeditor is missing initial <p> tags when inputting text to the editor. This causes the text to have an extra space "\n" added as it goes thru antisamy when published (also stored in the database in that way).
Pressing enter in editor (for input spanning multiple lines) <p> tags are added and thus does not reproduce issue.
1. Add Calendar portlet to page
2. Click 'Add Event', enter title, enter "abc" for description
3. Highlight "b" and bold it
*Notice that if you click 'Source' in CKeditor toolbar, the input is not enclosed in <p> tags
Text should be displayed as "abc"
Text is displayed as "ab c", with the added space after the html bold tag
