(core) Avoid reporting unhelpful ResizeObserver error

Summary: The error appears to be benign and not caused by any of our code.

Test Plan:
Reproducing was tricky.

On the Access Rules page, changing the browser's zoom level caused the error to surface. Weirdly enough, it only happened when connected to a larger, external monitor, and not on my laptop's internal monitor.

In any case, manual testing was done to confirm the error is no longer reported to the user after this change.
