zsh-autosuggestion breaks zle-isearch-update widget

[docwhat]

It seems that zsh-autosuggestion is breaking the zle-isearch-update widget, which is loaded for use by zsh-syntax-highlighting. I troubleshot this problem in zsh-users/zsh-syntax-highlighting#387 if you want to see the history.

Basically, if the zle-isearch-update widget is rebound and history-incremental-pattern-search-backwards is bound to ^R then search fails after a (small) random number of items in the history.

I created a minimal test case for you: https://gist.github.com/docwhat/0cd192c066a5f9da69244f1631c5d481

Clone it, run ./setup.sh and then ./fake-home.sh and try to search backwards for hi via ^R.

A work around for this is to add zle-isearch-update to the widget ignore list.

I also submitted PR #206 which would also fix this, via a sledge hammer.

Thank you for this. I will investigate soon.
