Creating a new "parent" number after a "child" number in a numbered list resumes from an incorrect value

Here’s a screen recording (using “tab” and “enter” to create different levels in the list):

After the “Second sub item” is written, the enter key is pressed twice to create a new “top level” item, but the number used is taken from the “sub list” rather than as a continuation of the parent list

But it parses okay in reading mode?

The editing mode numbers don’t really matter. You can select the entire list and toggle numbering off and on: that should put things ‘right’ in editing mode for you.

Thanks @WhiteNoise - this does look like a dupe of that one
