Subject: add DidInstallConditionalFeatures
|
|
|
|
This adds a hook on script context creation _after conditional features
|
|
have been installed_. Electron uses this to run preload scripts and
|
|
various other initialization. This is necessary because at the time
|
|
DidCreateScriptContext is called, not all JS APIs are available in the
|
|
context, which can cause some preload scripts to trip.
