    Seeing in 2019.1.0b7. Chrome/Firefox/Safari. Obvious/easy to reproduce (see @BEARD-OR-DIE's link above). Hello QA, anyone testing?

    Looks like what occurs that causes the freeze is a Javascript error within JS bundle.min.js: NotSupportedError: Operation is not supported

    This is happening for me, too, in Opera and Chrome for WebGL build from Unity 2019.1.0b5. See it in action here:

    We're facing the same issue in 2019.1.0b5. Was working before upgrading from 2018.2.0b9.
