iOS 14.2 beta crash

[nevets963]

Description

When running deck.gl on iOS14.2, it crashes safari and doesn't function at all.

Repro Steps

Load any example from here: https://deck.gl/examples

Environment (please complete the following information):

• Framework Version: Unknown, whichever version is used with the examples
• Browser Version: Safari
• OS: iOS14.2

I've tested the following versions and they all yield the same crash: 7.0.10, 7.3.15, 8.2.8 and 8.3.0-alpha.1

Logs

There are no errors or issues reported within the Safari console that I could see

Can you check if WebGL2 is enabled in this version? (see if WebGL2RenderingContext exists in the console)

[nevets963]

No, it's not there (it's undefined)

Update: not sure if this is useful, but WebGLRenderingContext does exist

Maybe something strange is going on with iOS 14.2? Sounds like Babylon.js is experiencing a similar issue https://forum.babylonjs.com/t/babylon-js-does-not-work-on-ios-14-2-safari-browser/14447

A bug has been identified and I believe fixed within Webkit: https://bugs.webkit.org/show_bug.cgi?id=217084

Thank you for following up on this!

I just installed 'iOS 14.2 Developer Beta 2' and Apple has resolved this issue.
