When touching shared runtime state, mutate only what your code owns and make failures diagnosable

Summary#

The React runtime fixes highlight two related lessons: broad cleanup logic can erase third-party state, and loose error handling can hide the first real failure. A safer pattern is to track the exact properties or listeners your layer owns, clean up only those, preserve the primary exception, and add regression tests around integration edges.

Problem#

Generic reset and event-dispatch code in shared environments can clobber extension-managed state or swallow the original error, making cross-system bugs hard to reproduce and debug.

Solution#

Scope cleanup to previously committed or explicitly owned state instead of clearing everything that looks removable. Tighten listener or event types, surface the first thrown error while still reporting subsequent ones, and add regression coverage for third-party integration paths.

Failure Modes#

Resetting singleton or global objects by deleting broad sets of attributes
Overwriting or removing properties set by extensions, scripts, or downstream consumers
Catching multiple listener failures but losing the original exception that explains the bug
