Not compatible ie11

[philipseo]

ENG Translate
SCRIPT5007: Cannot get property '__handlers' that is undefined or null reference.

I'm using the versions of the list below.
next.js 11.1.2
swr: 1.0.0

I checked similar issues and tried all the settings at the bottom of the issue, but the same error continues to occur.
ISSUE : #278

I would appreciate it if you could let me know which part to check or try.

I'm also seeing an error in IE11 on a page that only uses SWRConfig from swr:

Invalid calling object

Here's a reproduction: https://csb-13fdo-m9yttv7sk-amann.vercel.app/ (source)

It seems like it comes from the assignment of document.addEventListener to the variables onDocumentEvent and offDocumentEvent.

@philipseo I've added #1463 which solves the bug that I was seeing.

I couldn't reproduce your bug though. I'm currently using SWRConfig, useSWR and useSWRImmutable in my code base. These APIs seem to work in IE11 with the fix from the PR.
