-/**
- * Sandbox wrapper where [createWindowContext] provides contexts that are still sandboxed within
- * [application].
- *
- * Taskbar can create window contexts, which need to operate under the same sandbox application, but
- * [Context.getApplicationContext] by default returns the actual application. For this reason,
- * [SandboxContext] overrides [getApplicationContext] to return itself, which prevents leaving the
- * sandbox. [SandboxContext] and the real application have different sets of
- * [MainThreadInitializedObject] instances, so overriding the application prevents the latter set
- * from leaking into the sandbox. Similarly, this implementation overrides [getApplicationContext]
- * to return the original sandboxed [application], and it wraps created windowed contexts to
- * propagate this [application].
