It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging. If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group. |

Code Review
This pull request introduces manual tracking and disconnection of the 'delete-event' signal for the top-level window in FlView. The review feedback identifies a bug in the disposal logic where the signal is disconnected from the engine instead of the window. Additionally, it is suggested to refactor the implementation using g_signal_connect_object to automate signal cleanup and eliminate the need for manual ID management.

Is copilot right here? My knowledge of gobject signals isn't as robust
