…#9836) (cosmos#9841) * fix!: Capability Issue on Restart, Backport to v0.43 (cosmos#9836) <!-- The default pull request template is for types feat, fix, or refactor. For other templates, add one of the following parameters to the url: - template=docs.md - template=other.md --> ## Description Closes: cosmos#9800 The following is a breaking fix to cosmos#9800. In the non-breaking fix, the initialization logic was moved out of `InitializeAndSeal` but the API was preserved. I've now removed `InitializeAndSeal` and replaced it with just the `Seal` function, which may be called much more cleanly in `app.go` --- ### Author Checklist *All items are required.
