Revert "feat: Proxy extHost load module through messagePort"
Issue: gitlab-web-ide#331 (closed)
Description
This reverts merge request !76 (merged)
See fix: remove messagePort hack for crossOriginExt... (gitlab-web-ide!313 - merged) for the gitlab-web-ide
MR that reverted the change on it's end. Please note that the Web IDE crossOriginExtensionsHost
is still used (see relevant discussion issue https://gitlab.com/gitlab-org/gitlab-web-ide/-/issues/344). It's just this message port stuff we don't want anymore.
