Wait for hydration of various ionic components if they exist

Editor assessment

The subject states the timing guarantee concretely: nav waits for hydration of the Ionic components if they are present, which names both the condition and the guard. refactor(nav) is a defensible type for reordering initialization, and the scope is exact. No body or footer; the subject describes the mechanism precisely and the pull number gives provenance. Wording is compact and clean. Proportionate for a boot-sequence adjustment.
