Actual Behavior

The toast notification for some actions (like "sketch saved") doesn't get announced by the screen reader

Expected Behavior

Since a toast is a notification, it should be announced in a timely manner particularly since the toast will go away.
Sometimes a toast like "autosave enabled" does get announced.
I think there is an ARIA live region encapsulating the toast, but since the toast element would disappear from the DOM once visibility is switched off, the live region cannot be announced in due time.

Thoughts on approaching this and similar issues:
1).Set an announcement live region in the page, and update it whenever any status update sent in a toast happens.
2). Increase the duration of the toast might be helpful for giving enough time for the user to finish their action

Steps to reproduce

Steps:

1. Open a sketch on editor.p5js.org
2. Login with your credentials
3. Open up a screen reader
4. Edit and save a sketch
5. The toast shows up "Sketch saved", however, it doesn't get announced by the screen reader.

Snippet:

// Paste your code here :)

Reproduce the missing announcement in editor.p5js.org with Chrome and a screen reader, then locate the toast implementation and its ARIA live-region behavior. Compare the "Sketch saved" and "autosave enabled" cases; done means toast status messages are announced before disappearing, with coverage for the affected actions if the repository provides tests.
