[BUG] Regressions with "graphql-sse" subscription handling with altair-static.

[MurrayFurtado]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I have migrated from v7.0.1 to v8.0.5 and observe the following problems:

I configure initialSubscriptionRequestHandlerId: "graphql-sse" in my RenderOptions object and pass this to the renderAltair() method, along with a query and a subscription endpoint. When I click on run subscription I notice that once the subscription returns, it continually re-executes the query until I press cancel and it appends the duplicate results in the results window.

Secondly when I open the Request Handlers dialog I expect my Subscription Handler value to be set to Graphql Over SSE but it's still set on "websocket".

All this functionality used to work in v7.0.1 (except I had to specify initialSubscriptionsProvider: "graphql-sse" instead of initialSubscriptionRequestHandlerId)

Expected Behavior

When I click on run subscription it should just run my subscription query once.
When I open up the Request Handlers dialog I should see my Subscription Handler set to Graphql Over SSE

Steps To Reproduce

Problem manifests when initialSubscriptionRequestHandlerId: "graqhql-sse" with a given query.

Environment

- OS:  Windows
- Browser:   Chrome
- Platform:  ?
- Version: v8.0.5 of altair-static
