change order of list items introduces an unnecessary space for "9."

What is the problem?

I have a markdown file with a numbered list of items. When changing the order using Alt-Up/Down it works fine and automatically renumbers, but when the item I am moving passes from 9 to 10 there is an extraneous space left after “9.”, making it two spaces and that is getting caught by markdown lint.

How can I reproduce it?

1. Create an ordered list with at least 10 items.

List now may look like this:

1. a
2. b
3. c
4. d
5. e
6. f
7. g
8. h
9. i
10. j

1. Move item 9 one step down (i.e. switch place with the 10th item). Notice an extra space has been added after “9.” making the list look like this:

    1. a
    2. b
    3. c
    4. d
    5. e
    6. f
    7. g
    8. h
    9.  j
    10. i

Is there any error message in the console?

No

I’m using 2019.07.21.

I’d like to add 2 test cases. I think it’s pretty possible that someone embeds a code block into a list item. (| means cursor)

This test covers the case that the content of the previous list item is an indented code block:

<!-- Right after moving line 10 up -->
8.     eight
10. ten|
9. nine

<!-- Renumber -->
8.     eight
9. ten|
10. nine

This test covers the case that the content of the current list item is an indented code block:

<!-- Right after moving line 10 up -->
8.  eight
10.     ten|
9.  nine

<!-- Renumber -->
8.  eight
9.     ten|
10. nine

@yzhang-gh , would you please create some labels, such as Area-List, Area-Math, Area-TOC, Area-Preview-and-Print, Area-SyntaxHighlighting, Area-IntelliSense-and-Completion, to sort issues by area (subject or related function)? I believe that issues in the same area are related in some aspect. And if we get them together, we can possibly find the cause of a problem more accurately.

Besides, it would be nice to have a label called “resolved” to mark those are fixed in dev build but haven’t been released.

I have seen the same problem today. It causes markdownlint to mark the affected lines with multiple errors

Use case:

1. Create an ordered list with >= 10 items
2. Delete one of the items at index < 10
3. List item indexes are correctly updated, but the spacing is not
4. Markdownlint marks this as multiple errors:
   • MD030/list-marker-space: Spaces after list markers [Expected: 1; Actual: 2] markdownlint (MD030)
   • MD032/blanks-around-lists: Lists should be surrounded by blank lines markdownlint (MD032)

I haven’t checked, but if the same logic is used for all index magnitude indenting then the issue will be repeated at list index 100 and list index 1000.
