## Implementation Summary ### Changes Made: 1. **Added hidden prs input to issue detail modal** (server/templates/modals/issue_detail.html:165) - Added hidden input for PRs to mirror the existing repos-hidden pattern - The hidden input is included in the form submission when Save is clicked 2. **Created E2E test file** (tests/e2e/test_update_issue_prs_comma_separated.py) - 5 test cases mirroring TRCKR-582 repos tests: - test_update_issue_with_multiple_prs_comma_separated - Basic comma-separated list - test_update_issue_prs_with_spaces_trimmed - Spaces are trimmed - test_update_issue_prs_empty_entries_filtered - Empty entries filtered - test_update_issue_prs_via_add_button_flow - UI flow via Add button - test_update_issue_replace_prs_with_new_list - Replace existing PRs ### Verification: - Template syntax validated via Jinja2 parser - Test file validated via Python compiler - Existing CLI tests for prs continue to pass ### Note: E2E tests were skipped during local testing because Docker was not running.
