mutate in useSWRInfinite is broken when passing data and revalidate true

Bug report

Description / Observed Behavior

When using useSWRInfinite, if we call the bound mutate function and we pass the data argument, the data is not updated or revalidated.

Expected Behavior

I expect useSWRInfinite to both update the cache and re-fetch data from source.

Repro Steps / Code Example

CodeSandbox

Notice how mutate(data) doesn’t update the cache or revalidate the data but mutate(data, false) does update the cache. mutate() revalidates with no issues.

Additional Context

SWR version. 0.4.0

I guess this is because the mutate function for useSWRInfinite is not updating the cached pages with the data parameter before calling useSWR mutate. When the infinite fetcher adapter runs, this is equal: config.compare(originalData[i], pageData). mutate from useSWR will just update the global cache key for the infinite list, not the individual pages as this code would assume

for workaround you can do:

mutate(data, false)
mutate()

the first one mutates the cache, the second triggers revalidation.

forgot to save my sandbox before sharing. it should be okay now
