## Fix Summary Added comprehensive E2E Playwright tests for changing an issue's milestone from one milestone to another. ### Changes Made Created tests/e2e/test_update_issue_change_milestone.py with 5 test cases: 1. test_update_issue_change_milestone - Basic test for changing milestone from one to another via the detail modal PropertyDropdown 2. test_update_issue_change_milestone_using_search_filter - Tests using the search input to filter milestones before selection 3. test_update_issue_change_milestone_with_multiple_milestones_available - Tests selecting the correct milestone when multiple options exist 4. test_update_issue_change_milestone_back_and_forth - Tests changing milestone multiple times (ping-pong pattern) 5. test_update_issue_change_milestone_preserves_other_fields - Verifies that changing milestone doesn't affect title, status, priority, or project ### Helper Function Added create_issue_with_milestone() helper to create issues with an initial milestone assigned, which is needed to test milestone changes (not just setting from none). ### Verification All 5 tests pass successfully.
