events can sometimes be posted before angular is ready. Waiting for angular seems to fix the issue.
seems the vue files weren't updated for some reason. Will merge in latest 4.x-dev, maybe that triggers the build.
@diosmosis I guess I know why the vue files didn't built. The action only ran on
synchronize, but seems that isn't triggered when the PR is opened. As you didn't push any further commits afterwards it was never triggered. I've added a commit so the action should also run when a PR is opened. Feel free to have a look and merge if you think that's fine.
