One taxonomy term selected, multiple terms applied

[aljuk]

I have a client site with a custom taxonomy that has quite a few terms (130). Selecting some terms is suddenly problematic.

When my client creates a new post and selects a particular term to apply in the post editor, two other terms are automagically being selected without her interaction. She selects (checks) one term to apply in the post editor, and ends up with three.

Upon investigation, all three terms have IDs that begin with the same two digits.

The term she selects has ID 67. The other terms that are being automagically added are terms with IDs 673 and 678. There are no other terms in the list whose IDs begin with 67, just these three. I’ve tested myself, and if term with ID 673 or term with 678 is selected, no problem, only that single term is checked. Check 67, however, and all 3 become checked.

I can’t find a logical solution. I think it may be a bug in WP. I’m just awaiting a client response, but I believe this has started happening with the most recent WP update.

I've rolled back to WP 6.6.2 and the problem has gone away ...

Hii @aljuk
I have tried to replicate the issue with term IDs 4 and 41 on WordPress version 6.7.1.
But for me, it is working fine. If possible can you please attach a screen recording of the issue you were facing for ver 6.7.1 for more clarity.

It's happening for the categories that have the popular-categry class

The problem is from post.min.js

h("#" + a + "checklist, #" + a + "checklist-pop").on("click", 'li.popular-category > label input[type="checkbox"]', function() {
            var t = h(this)
              , e = t.is(":checked")
              , i = t.val();
            i && t.parents("#taxonomy-" + a).length && (h('input[id^="in-' + a + "-" + i + '"]').prop("checked", e),
            h("input#in-popular-" + a + "-" + i).prop("checked", e))
        })

Hi and thanks for the report!

The issue with category selection in the (classic) post editor is already tracked on #62504.
