Loading remote extractors crashes mobile safari

[LucasThompson]

Environment: iOS 10.3.1 iPhone 7

Steps to reproduce:

• Load app
• Open extractors tab
• Click "Load remote plugins"
• Safari reloads with error notification "A problem occurred with this webpage so it was reloaded"

This happens quite consistently from a fresh load of the page, no audio loaded. Sometimes when audio is already loaded and some analyses have been performed, it doesn't happen. I haven't investigated much further.

I've not been able to reproduce using the iOS Simulator, and there are no issues on safari on desktop.

Some work has been done on this here, but it seems to not have resolved the issue. More investigation needed.
