Reviewing injected content without aria-live

The container below has been not been set with any aria-live value.

• Action: After 8 seconds, a message will be injected into the container below. Focus will be sent to the message container.
• Result: The injected content should be announce as it has received focus.

Example

If a screen reader is focused on announcing this paragraph, will the dynamically injected message above affect the announcement of this paragraph? This is how we can determine whether dynamic information is announced immediately, at the next graceful opportunity, or not at all.
