Error with Builder.up depending on context

[H-L]

Hello,

I encountered an error using Strophe in Workers, compiled as a dependency. It appears that the method Builder.up() is using this.node = this.node.parentElement; but in this particular context, node.parentElement does not exists.

I patched it locally, replacing it by node.parentNode and it seems to work.

I don't know if it would have side effects to change it directly.

Let me know if you need a PR.

Best regards

Hi, I would appreciate a PR, thanks. I think for backwards compatibility, the code could use parentElement if it's available and fall back to using parentNode if not.
