WYSIWYG Editor changes bullet lists when inserting blank line in before

When creating a bullet list in the WYSIWIG editor and then adding a new paragraph ending with a new line in front of this bullet list, the first item of the bullet list is displayed as asterisk.
For example, a list

• test
• test2

will become following Wiki markup:


* test

• test2

Before saving it looks ok (circles instead of asterisks) in the editor view.

This also seems to happen if there are blank lines preceding a bullet list somewhere in the page and the page is just saved (neither the bullet list or the paragraph being changed).
