On an Incident form with a reference field (A) and a dot-walked field (B) and an embedded list on the form with a reference field (a) that points to the same table as the other reference (A), when inserting a row on that embedded list by double-clicking the empty reference field (a), the dot-walked field (B) clears. This does not occur if you double-click another field in the list that is not referenced on the form.
Steps to Reproduce
Navigate to Incident > Open and open an incident.
Right-click in the form header and choose Configure > Form Layout.
Use the slushbucket to add configuration_item.manufacturer (in some versions of the form it's known as affected_ci) to the form layout underneath configuration_item and click Save.
Add Problem > Task embedded list to the form underneath the two configuration items and click Save.
Test the problem by setting the Configuration item field to a value that has an associated manufacturer.
Note that configuration_item.manufacturer has updated to reflect the dot-walked field.
Double-click underneath configuration_item on the embedded list.
Note that configuration_item.manufacturer has been cleared.
