onTableResize is called after test teardown

[steveszc]

I've observed that in certain acceptance test scenarios that I don't fully understand yet, ember-headless-table's resizeObservers can trigger onTableResize after the test has been finished and the app has been torn down.

This redacted screen shot was captured on an uncaught error in an acceptance test.
The stack trace shows an error originating from a controller property that is being re-evaluated after the controller is destroyed, and shows the trace originating back to onTableResize which leads to the rowSelection plugin being re-evaluated, which re-evaluates our controller getter.
The anonymous call at the root of the stack trace references the ResizeObserver callback here: https://github.com/CrowdStrike/ember-headless-table/blob/main/ember-headless-table/src/plugins/column-resizing/plugin.ts#L392-L396

I attempted to add an isDestroyed(table) guard to the ResizeObserver callback, but it did not appear to resolve the issue, which indicates that the table is not being destroyed when it should.

any chance you have a reproduction app?

I don't understand how to reproduce this... but I can reliably reproduce it on a project that isn't available publicly.

maybe an application test that explicitly calls destroy(this.owner) and then triggers browser resize?

I have tried and thus far failed to get a reproduction, current state of that work is here: https://github.com/steveszc/ember-headless-table/blob/sszczecina-issue143-repro/test-app/tests/application/table-test.js
