(/**
|
|
* Pierce the extension sandbox by copying our code into window space.
|
|
*
|
|
* The isolation extension content scripts get is neat, but it causes problems
|
|
* based on what browser you use:
|
|
*
|
|
* 1. On Chrome, you are explicitly banned from registering custom elements
|
|
* 2. On Firefox, you can register custom elements but they can't expose any
|
|
* useful API surface, and can't even see their own methods.
|
|
*
|
|
* This code exists to pierce the extension sandbox, while maintaining:
|
|
*
|
|
* 1. The isolation of not interfering with the page's execution environment
|
|
* unintentionally.
|
|
* 2. The ability to load extension resources such as .wasm files
