Nested list under Ordered list with "Indent size" set to 2 incorrectly shows warnings

[ni-fgenois]

When the "Indent size" is set to 2, I would expect the following snippet not to show a warning :

1. Item
  - Sub-item A
  - Sub-item B

The recommended fix is (4 indents) :

1. Item
    - Sub-item A
    - Sub-item B

But this also works (3 indents) :

1. Item
   - Sub-item A
   - Sub-item B

Note that this only happens when the root item is an ordered list, the following doesn't show a warning, as is expected :

- Item
  - Sub-item A
  - Sub-item B
