Error in safari mobile 10.3

[felipeegasneris]

Hi, I'm building a component and testing it on safari mobile 10.3 and I getting this error: TypeError: The Element.shadowRoot getter can only be used on instances of Element on this line: this._container = new Container(renderer, this.shadowRoot, this); do you know why is this error? I need to make works haunted on Safari 10.3, please help me :(

Thanks for reporting. We'll figure it out. Sounds like this is not an element. That's odd. What is this? there, can you inspect that?

inspecting this, I get: this: "TypeError: The Node.ownerDocument getter can only be used on instances of Node"

any clue on that @matthewp ?

Can you give me a minimal example so that I can take a look? I don't think that version of Safari supports modules so my examples I have don't run on it. I guess you probably need a bundled app. If you can give me a minimal example I'll try to debug it.

I ran into the same issue as @felipeegasneris. I created this reproduction branch: https://github.com/Neovici/cosmoz-image-viewer/tree/haunted-bug-repro

Just do npm start and open http://localhost:8080/dist/index.html in Safari 10.

Cool, thanks for the reproduce!

No, sorry. It's unlikely I'll personally be able to get to this any time soon. I would love a PR that fixes it.

This looks to be fixed. I just tested via iOS Simulator -- I can repro per the above steps on iPhone 7 in iOS 10.3.1, but no error & page w/ image loads fine in 11.3, 12.4, 13.5 (iPhone 8).
