Issues with Suspense/lazy in Preact 10.0.1

See original GitHub issue

I am using Parcel + TypeScript + Preact and when i upgraded from Preact version 10.0.0 to 10.0.1 I started to get an error with Suspense.

Uncaught (in promise) TypeError: Cannot read property 'indexOf' of null
    at t (suspense.js:64)

All that changed was the patch version of Preact. I have a repository showing the issue and my settings here: https://github.com/nrdobie/preact-10.0.1-issue. The master branch uses 10.0.0 and broken branch uses 10.0.1

Main Packages Versions:

parcel-bundler@1.12.4
typescript@3.6.4
preact@10.0.1

Fix has been PR’ed, thanks for the reproduction this helped me to tackle the problem. It’s a bit of a bad luck one to be fair. The thing is that it wasn’t safe for _suspensions to exist without mangling this would mean that terser is safe to mangle it to whatever it wants which can interfere/be overwritten.

This has now been pinned to __u.

@darklight9811 Please file a new issue for this if you want it to be resolved.
