Tagify not outputting value field in mix mode

I am trying to allow users to ‘@tag’ each other within a comments text input, and I understand this requires the tagify mode being set to mix. However, when the mode is set to mix, the text input does not output the user_ids (tagify value field) as expected, only the names (tagify text field) of the users who have been tagged.

The tagged user_ids are outputted when the tagify mode is set to default, however, it does not seem to work when the mix mode is selected.

Has anyone else come up against this issue, and does anyone have any workarounds?

The tagify element though not exposed for you in the UI, still has .items and .values available. You can use a hidden element with a value of tagify1.values to get those sent with your form POST.

Thank you!
