Tell about a case from your experience where a detected defect had a low level of importance but was highly serious for the system.

In one of the projects, I discovered a bug related to the incorrect display of a minor interface element — for example, a status icon in the admin panel. From a business perspective, this element did not affect core functions and did not interfere with users, meaning it had a low level of importance. However, from a technical standpoint, this defect indicated a problem with component rendering, which could lead to failures during system scaling or updates. Thus, despite its low priority from the user's point of view, the defect was highly serious for the stability and support of the system in the future.
