Closes #37601 Regressed in https://github.com/zed-industries/zed/pull/36469. Edit: Original issue https://github.com/zed-industries/zed/issues/25744 is fixed for Zeta in this PR. For Copilot, it will be covered in a follow-up. In the case of Copilot, even after discarding, we still get a prediction on suggest, which is a bug. Release Notes: - Fixed issue where predict edit at cursor didn't work when `show_edit_predictions` is `false`.
