         `ResourceAllocationFormItems` internally uses several
         `useLazyLoadQuery` calls that suspend whenever the watched
         form values (resource group, image, allocation preset) change.
-        Those throws are caught by the modal-level Suspense fallback
-        above the form body — combined with the deployment query's
-        default `store-or-network` policy, the body remounts re-read
-        the cached deployment instead of re-fetching it, so the
-        previously observed infinite-fetch loop does not recur.

+        unmounting the entire form body and losing user input.
