zsh-syntax-highlighting: Widget binding ignores are breaking hchbaw/opp.zsh

If I use both zsh-syntax-highlighting and opp.zsh, opp produces an error whenever a new shell is started:

(eval):1: bad pattern: orig-opp-gps-( opp-gps-(
(eval):1: parse error near `)'
(eval):1: parse error near `;'
(eval):1: parse error near `;'
(eval):1: bad pattern: orig-opp-gps-[
(eval):1: parse error near `}'

I was able to narrow it down to zsh-syntax-highlighting, and discovered this behavior was introduced in 18df692. The previous commit (7044c19) works fine.

My zshrc is available here: https://github.com/zhimsel/dotfiles/blob/master/zshrc That should be current and live on my machine.
