Checkboxes in Issues updating the wrong checkbox

Summary

  • In some circumstances, checking a box in an issue description updates the checkbox for a completely different checkbox.

Steps to reproduce

  • This is currently reproducable in the groupcompliance planning issue for %13.9

  • Attempt to check the box next to one of the features. Optional enforcement of SSH key expiration definitely triggers this bug.

  • Once checked, refresh the page. The checkbox is no longer checked, and a different one further down the page is. The event log also confirms this.

  • The GraphQL query made also matches the incorrect behaviour.

  • The lists appear to need to be in a table to cause this bug.

Example Project

What is the current bug behavior?

  • Check one box
  • A different one is checked in the backend and this is visible on page refresh.

What is the expected correct behavior?

  • Checking a box in an issue description should check the correct box.
