Editor ignores current indentation when creating new list item

[mbaum0]

Describe the bug

The text editor ignores the current indentation level when adding an item to a list. After pressing enter, the next list item is created with all indentation removed. This makes writing sub-lists tedious, as you have to manually add whitespace.

Steps to reproduce

1. Create a list item
2. Start a sub-list and add the first item
3. Press enter to add another item
4. See that the cursor creates another item at the parent's indentation level.

The version of Memos you're using
