Click "Cancel", "X", button doesn't show Unsaved changes modal when there are warn/fail errors in quickmarc

Overview: Click "Cancel", "X" button (or “ECS” key) doesn't show Unsaved changes modal when there are unsaved changes and displayed warn/fail errors in quickmarc.
Reproduces for MARC bib/authority/holdings - create/edit/derive.

Steps to reproduce:

1. Open MARC record via quickmarc in Create/Edit/Derive mode

2. Update any field (create unsaved changes, which will trigger Warn of Fail error)

3. Click on the “Save & keep editing”/”Save & close” (warn or fail error must appear)

4. Click on the “Cancel” / “X” button / Hit “Ecs” keyboard key

Expected result: Display the Unsaved changes “Are you sure” modal
Actual result: Quickmarc pane is closed without “Are you sure” modal appearance.
