Bug Description

Jumping to discussion tree from reviewer doesn't work when the Notes tab is open.

Reproduction Steps

1. Check out the feature branch
2. Open Neovim and start a review
3. Create two comments.
4. Switch the discussion tree view from Inline comments to Notes
5. Go to the second comment in the reviewer (it has to be the second one so that the cursor position is outside the buffer, see the error message below)
6. Press the "Move to discussion" keymap (a by default)
