Subject: Adjust accessibility_ui for Electron
|
|
|
|
This tweaks Chrome's Accessibility support at chrome://accessibility
|
|
to make it usable from Electron by replacing use of the Profile PrefService
|
|
with Electron's own PrefService in ElectronBrowserContext. It also removes
|
|
usage of BrowserList and Browser as we subclass related methods and use our
|
|
WindowList.
