Pasting a list with sublists only indents first sub-list (3.6.1 and up)

[jorp]

I attached a test document with a simple nested list. Please paste the list into a ckeditor field.

Expected Results: Item 1 and Item 3 sublists should be indented.

Actual Results: Only Item 1 sublist is indented.

The behavior worked fine in 3.6.

Test case

Pasting lists got broken somewhere between rev [6909] and [6913].
Those revisions don't work so I can only guess, based on a comment, that has happened in [6911].

Probably form rev [6911] list was pasted without indentations (was flat). You can verify it looking at samples from rev [6914].

From rev [6977] when list from the above doc was pasted its "item 2" was missing but all the other elements were indented.

From rev [7008] result is the same as described by @jorp - only first element gets indented.
