### What?
Set the `limit` query param on API requests called within the
`useLivePreview` hook.
### Why?
We are heavily relying on the block system in our pages and we reuse the
media collection in a lot of the block types. When the page has more
than 10 images, the API request doesn't fetch all of them for live
preview due to the default 10 item `limit`. This PR allows the preview
page to override this `limit` so that all the items get correctly
fetched.
### Our current workaround
Set the `depth` param of `useLivePreview` hook like this:
```
useLivePreview({
// ...
depth: '1000&limit=1000',
})
```
