Which platform(s) does your issue occur on?

iOS

Please provide the following version numbers that your issue occurs with:

cli 4.0.2
runtime: 4.1.0

Please tell us how to recreate the issue in as much detail as possible.

Unfortunately it's a race condition. No real reliable way to repro other than it happens occasionally and can crash an app on iOS 10 and below.

PR coming.
