Route status conditions about detached parentRef

[vaniog]

Situation

• Create two valid gateways: gateway1 and gateway2.
• Create a valid HttpRoute called httproute1 with a parentRef to gateway1.
• A condition RefsResolved: True will appear in the parent status associated with gateway1.
• Change the httproute1's parentRef to gateway2.
• A condition RefsResolved: True will appear in the parent status associated with gateway2.
• The condition related to gateway1 does not disappear.

What did you expect to happen:
Old condition to disappear.

Anything else you would like to add:
I believe the issue is with this (https://github.com/projectcontour/contour/blob/main/internal/status/routeconditions.go#L145) function, which seems to ignore other parent statuses. As a result, the parent status related to the non-existent parentRef persists indefinitely.

Environment:
contour 19.5.6
kubernetes client v1.27.3
kubernetes server v1.29.1
yandex.cloud
ubuntu
