Describe the bug

When using WrapFields a larger number of times across multiple handlers, a graphql.visit invocation gets increasingly slower. I observed that the selection set in the visited document increases in powers of two for some reason. I'm not sure exactly why but after debugging it is a result of this bit in TransformCompositeFields.

To Reproduce
My implementation is complex (and the issue seems to be a result of that complexity) but because the fix seems harmless I thought I'd report it before trying to reproduce in a minimal example.

Expected behavior

The visit function is not stuck in a loop.

Environment:

• OS:
• @graphql-tools/...:
• NodeJS: 16
