Adding a list removes preceding empty line with enterMode = CKEDITOR.ENTER_BR

[Claas Augner]

Problem

When using the CKEDITOR.ENTER_BR enterMode, adding a (numbered or bulleted) list after an empty line removes this preceding line.

Steps to reproduce

Step 1: Go to http://sdk.ckeditor.com/samples/enterkey.html

Step 2: Choose When Enter is pressed: Break the line with a <br> (Screenshot 1)

Step 3: Add the following text:

Line before empty line

First item

(Screenshot 2)

Step 4: Move the cursor to the line containing First item and press:

(Screenshot 4)

Expected behavior: A list is created with First item as its first item, leaving the preceding line intact. Actual behavior: The list is created, but the preceding line is removed (*).

(*) Note that in the example there is a margin between the first line and the list, so that the removal of the line is not necessarily noticable (especially in the example):

Solutions

The behavior of adding a list (same holds for indentation using the indentblock plug-in) should be changed so that it does not remove a preceding empty line.

It might be desirable to make this behavioral change configurable in order to maintain backward-compatibility.

As for this issue I don't see a strong reason why you'd need a <br> before list, since lists are by definition a block elements, and as such require line break. But that's something that should be discussed on Trac.

Note that converting First item to a list has the same result for the following inputs:

Line before empty line

First item

Both basically result in this (leaving aside CSS styling):

Line before empty line
- First item

However, I would argue that in the first example the user's intension was to separate the Line before empty line from the list explicitly by one empty line.
