Relative line number jumps don't work

Please thumbs-up 👍 this issue if it personally affects you! You can do this by clicking on the emoji-face on the top right of this post. Issues with more thumbs-up will be prioritized.

Commands like number + j or number + k take you to the wrong line number.

Steps to reproduce

1. Open any file > 20 lines of code
2. In Normal mode type 14j or 14k (use any number greater than 12)
3. Notice how the cursor jumps more than 14 lines

Please let me know if you need more steps to reproduce

Cursor on absolute line 43

Command ran 14k

Start by reproducing 14j and 14k in a file longer than 20 lines, using the reported VSCodeVim settings, especially the accelerated cursor mappings and relative line numbers. Compare the resulting cursor position with the requested count and verify the behavior without those custom mappings. Done means counted jumps land on the expected line without breaking the reported configuration.
