Bug: React logComponentRender breaks existing functionalities that utilise proxy (trpc client)

[bimusiek]

client[procedureType] is not a function

React version:
19.2.3

The current behavior

When trying to read properties of the object to show the diff in log, it breaks it.

The expected behavior

Should work.

I am not sure if this is to be fixed on React side or TRPC, but it worked in previous versions of React.
