     *
     * Every periodic network polling should be paused while this is set
     * to `false`. Extensions should use this value to decide whether to proceed
     * with the polling.
     * The extensions may also set this value to `false` if there is no need to
     * fetch anything from the server backend basing on some conditions
     * (e.g. when an error message dialog is displayed).
     * At the same time, the extensions are responsible for setting this value
     * back to `true`.
