History not synced accross terminals.

[ysftaha]

Reproduce by executing a command in one terminal and calling history-substring-search-up in another. Does not work unless sync or rehash is executed in the later terminal first.

adding

rehash_hook() rehash
add-zsh-hook precmd rehash_hook

The back searching across terminals works (default ^R) or on empty prompts...Only it isn't working for history-substring-search.
