Warning alert not emitted when warning audio cue not emitted

[rzhao271]

Testing #203089

"Audio Cues: Line Has Warning" is set to false. "Accessibility > Alert: Warning" is set to true.

I generated a warning by using the Markdown Lint extension and writing text into a new Markdown file without an h1 header. When I turn on the audio cue, the accessibility alert also alerts me that there's a warning. When I turn off the audio cue but leave the accessibility alert on, the accessibility alert does not alert me that there's a warning.

I cannot seem to trigger a warning - can you pls give more specific instructions about how to do so? @rzhao271

[rzhao271]

Install the markdownlint extension.
Then create a .md file and paste in the following

Hello world!

Another line here

The extension should already generate a warning.

Note this issue when verifying #203266. When I tested using a screen reader, the warning only appeared once. Based on debugging (the alert call happens), I believe when using a braille device, this works.
