[orca-list] Is this an Orca bug?

Hey folks,


I'm working on a web app that uses Bootstrap-Vue. The Bootstrap-Vue 
folks try hard to do accessibility right, but sometimes they mess up, 
and I'm not sure if this is one of those instances.


They have a toast component that displays popup notifications. The 
notifications use ARIA attributes,and there's a mechanism to dynamically 
make toasts appear, but that mechanism only reads any toasts subsequent 
to the first. So I'm wondering if the first toast appears with an ARIA 
live region and isn't read because it appears out of nowhere, and 
subsequent updates read fine because they're updating an existing region?


To see what I mean, visit 
https://bootstrap-vue.js.org/docs/components/toast/ and navigate to the 
demo under the "Toasts on demand" header and click the "Show toast" 
button. The first click speaks nothing, while the second click speaks 
both the current and previous toast.


If they're doing something wrong here, please let me know and I'll 
submit a PR. Thanks!
