Comment (by David Sanders):

 Replying to [ticket:34789 devin13cox]:
 > My initial guess is that updating the query to not include the "Chosen"
 column in filter_horizontal fields would solve this issue (something like
 > {{{
 > const selectsRelated = document.querySelectorAll(`[data-model-
 ref="${modelName}"] div:not(.selector-chosen) > select:not(.admin-
 autocomplete)`);
 > }}}

 That could work 👍 I'm just wondering though whether there's a better
 approach than to continuously blacklist ancestors as we come across these
 🤔
