Fixed by adding E2E test for bulk delete multiple issues with confirmation. ## Changes Made 1. Created tests/e2e/test_bulk_delete_multiple_issues.py with 7 comprehensive test cases 2. Fixed a bug in server/templates/base.html (line 4860-4862): - Added missing JavaScript aliases executeBulkActionIssues and clearBulkSelectionIssues - The bulk_toolbar macro generates executeBulkActionIssues() but only executeBulkAction existed ## Verification All 7 E2E tests pass locally.
