GraphiQL explorer does not look at default values set in Python

Reproduction steps:

1. Create a query with Python that has an input parameter that defaults to 1 (ex. a pagination query that defaults to "page: 1")
2. Open that query in the GraphiQL interface explorer
3. Click on the checkbox next to the input parameter and notice the value placed into the field

Expected Results
The input parameter would be set to 1

Actual Results
The input parameter is set to 10
