Thanks for the report, we're aware of this one and it's being tracked in multiple issues already. One of which is #4329, more specifically #5024. In the latter there is also a workaround being mentioned and it should be fixed for the next release. Thanks!

@jfversluis The workaround does not work :)

@jfversluis thanks a lot for the info, this is a show stopper as we can't push the app to production (workaround didn't work for me)
