Fixes #112526
This bug was introduced by #96102, which wants to update the pixels before determining what should be shown when the children's count changes.

The root cause of this issue,
If the children's count is indeterminate, it will apply unboundary dimensions which may break the BouncingScrollPhysics boundary.
