// The view class, which is owned by the `EmbeddedPermissionPrompt`, applies a
// scrim to the contents view on the root window while the permission prompt is

// web-content interaction while the user is interacting with the permission
// prompt.
// The `EmbeddedPermissionPrompt` is responsible for managing the lifetime of
// the scrim view and the in-progress `EmbeddedPermissionPromptBaseView`. When
// the prompt view is destroyed, the scrim is automatically removed. Clicking on
// this scrim view will destroy both the scrim view and the in-progress
// `EmbeddedPermissionPromptBaseView`.
