Applying a freeze effect while damaging a mob causes an incorrect value for ticks_since_last_hurt_by_mob

One of my data pack is designed so that when a snowball fired by a snow golem hits a mob, it freezes them. However, I've noticed that the mob's ticks_since_last_hurt_by_mob value fluctuates between 0 and 1 at this time, and skeletons are unable to fire arrows normally.

The Attachments folder contains the file for this data pack.
