https://stackblitz.com/edit/tanstack-router-5lj1t6?file=src%2Froutes%2Findex.tsx,src%2Froutes%2F__root.tsx&preset=node

Steps to Reproduce the Bug or Issue

	"@tanstack/router-zod-adapter": "^1.58.9",
	"@tanstack/react-router": "^1.82.0",

my on Filter/search change after debounce for search is something like

const onFilterChange = useCallback(
(v: T): void | Promise => {
navigate({
to: '.',
search: (c) => {
console.log('FilterBar.tsx:122', c)
const newValue = v

				const retunning = c
				if (!retunning.q) retunning.q = {}

				Object.assign(retunning.q, newValue, {
					page: c.q?.page ?? 1,
					search: search || undefined,
				})
				Object.assign(retunning, newValue, {
					page: c.q?.page ?? 1,
					search: search || undefined,
				})

				return retunning
			},
		})
	},
	[navigate,  search],
)

for this console log "FilterBar.tsx:122" all latest values are available while console log in route page is not updating
"""
const params = Route.useSearch()
console.log(params)
"""

Defination of searchValidation is done like
"""
export const ZodListQuerySchemaExtend = {
page: fallback(number().optional(), 1).default(1),
search: fallback(string().optional(), ''),
order_by: fallback(string().optional(), ''),

[QUERY_STRINGS.start_date]: fallback(DATE_ZOD_VALIDATOR, undefined),
[QUERY_STRINGS.end_date]: fallback(DATE_ZOD_VALIDATOR, undefined),

}
const searchSchema = z.object({
q: fallback(z.object(ZodListQuerySchemaExtend), { page: 1 }),
})
export const Route = createFileRoute('')({
component: Component,
validateSearch: zodSearchValidator(searchSchema),
})
"""

Expected behavior

console log in Component should be updated when url changes

I checked recreation of nested state with different object works but could that be mentioned on use search params docs for new object needs to be created ,as react state normally re run if first level object is recreated into new object so for garbage collection saving our product uses reassign to same object reference on nested object but for this case it goes differently than react state

Also I am aware of use memo and use callback not trigging on nested items if reference of nested item is not changed
