[3.2] Structure entries with no children showing expand arrow

[gregorterrill]

Description

After updating to 3.2, some entries in a structure with no children are showing the expand arrow next to them in the CP. If I inspect, I can see that the data-descendants attribute on those entries' table rows show a non-zero number, even though there aren't actually any descendants. Clicking the expand arrow causes a new row to flash in and then disappear.

I believe the affected entries previously had children which were later moved to be top-level entries themselves (long before updating to 3.2).

Re-saving the entry, creating and deleting a new child entry, and clearing all caches all don't clear the issue.

Additional info

• Craft version: 3.2
• PHP version: 7.1.18
• Database driver & version: MySQL 5.7.21
