Modal didn't disappear after split the discussion

Bug Report

Tag changing modal doesn't disappear when I split post from the original one to under the new discussion. I don't know it's happening because of FoF Split but I wanted to report it.

Steps to Reproduce

1. Go to a discussion
2. Click on arrow and click Spilt
3. Create a new discussion
4. Change the tag and save or close the modal

Expected Behavior
The modal should be closed after saving the changes or closing the model.

Start by reproducing the split flow in Flarum 1.8.5 with fof-split 1.1.1: split a post, create a discussion, then change its tag and save or close the modal. The issue is done when the tag-changing modal closes correctly after both actions.
