Cursor jumps to the top when pressing j or Ctrl-D on an empty last line

[basyura]

Description

When the cursor is on an empty last line, pressing j or <C-d> in normal
mode scrolls the note to the top unexpectedly.

I am not sure whether this is an issue in inkdrop-vim, CodeMirror, or the
CodeMirror Vim integration layer.

Steps to Reproduce

1. Open a note with multiple lines.
2. Make sure the last line is empty.
3. Move the cursor to the empty last line in normal mode.
4. Press j or <C-d>.

Expected Behavior

The cursor should stay on the empty last line, and the note should not scroll
to the top.

Actual Behavior

The note scrolls to the top unexpectedly.

Environment

• Inkdrop version: v6.0.0-canary.15
• inkdrop-vim version: 3.1.2
• OS: Sequoia 15.6.1

It looks like a Vim extension's bug, and it's been fixed already: replit/codemirror-vim#258
but hasn't been published yet.
I'll update the package when a fixed version is available.
