• check that it still runs in Edge

This is a partial revert of #3961 so better not backport to versions that need to support IE11.

Fixes #4818

[PVince81]

Tested with Edge, the page loads fine.

The last IE version is Nextcloud 22 IIRC?

I found this (still open) ticket on server: nextcloud/server#20855
As far as I understand:

• IE11 deprecated in NC 20, Edge still supported
• Edge still supported in NC 21, IE 11 not any more (which fits with my statement in this PR)
• Edge also dropped in NC 22

[PVince81]

we might not need to backport if we don't upgrade babel-env-preset in stable versions

[nickvergessen]

No, the ticket is IE11 will be deprecated but should be mostly functional until 22.
Edge is Chrome based and updates automatically, so not a problem at all.
But a blank page in talk is not "deprecated".

Another fix idea would be to downgrade the problematic lib again and add it to the ignore list of dependabot

[PVince81]

okay, so will retest with IE 11 to see if, by any chance, the old problem magically disappeared (ex: through recent babel updates):

• retest with IE 11

[PVince81]

with IE11 it does NOT work, an error about the event bus appear:

as we can see it did not get transpiled for IE 11

maybe the transpiling should be done in the repo itself ?

also, it seems talk alpha 2 build is broken as well with IE 11 due to nextcloud-vue, raised here: #4820

[PVince81]

revert PR is here #4821

[PVince81]

right, so the problem is that semver is not transpiled: nextcloud-libraries/nextcloud-event-bus#145
