## Summary Added comprehensive E2E tests for updating issue repos field with comma-separated list values. ## Changes Made Created new test file `tests/e2e/test_update_issue_repos_comma_separated.py` with 5 test cases: 1. **test_update_issue_with_multiple_repos_comma_separated** - Verifies that setting the repos hidden input to a comma-separated list correctly saves all repos via the PATCH endpoint. 2. **test_update_issue_repos_with_spaces_trimmed** - Verifies that extra spaces around repo names are properly trimmed. 3. **test_update_issue_repos_empty_entries_filtered** - Verifies that empty entries between commas are filtered out. 4. **test_update_issue_repos_via_add_button_flow** - Tests the full UI workflow of adding repos one by one via the "+ Add" button. 5. **test_update_issue_replace_repos_with_new_list** - Verifies that setting a new comma-separated list completely replaces the previous repos. ## Verification All 5 tests pass against the local server.
