Hopefully will not be an issue in reactive chain manager.

On hold because of #320

Since the code around warp sync changed drastically in #320 and #568 (ChainManager and block dispatcher do not exist anymore) this can be closed.

@github-project-automation github-project-automation bot moved this from Backlog to Done in iota-core Dec 4, 2023
