Any additional comments?

Previous bug https://github.com/vuejs/core/issues/5513 was closed due to the introduction of the suspensible option. But the bug is still present even when using suspensible on Suspense. This issue is blocking https://github.com/vuejs/router/issues/1324 from closing

Just noting for reference, verified this is still a problem with vue v3.4.6
