That is an old ticket from 2018, from what I can tell it has something to do with IE11. Is it still relevant? Is it a problem that you encountered while using the graphql page?
Curious, since as far as I know, nobody has filed a ticket about it at go-ethereum.

because the fetch library is just a polyfill. and since 2017 all mainstream browsers have supported fetch. so even if the library has an error, it does not affect normal use.

imo, it can be removed now.

fyi, https://caniuse.com/?search=fetch

Can you please try this #27294 and see if you get the error there also?

Closing in favour of #27294
