Alt text not being read by aria-live region

[thatjack99]

Summary

The alt text of an image html tag is not being read in an aria-live region.

Here is one way to reproduce this: 1) Start with a div html tag with aria-live attribute 2) insert an image tag into the div with alt text. This can be done with a button 3) notice that the alt text for the image is not being read

Expected result

I expect the alt text to be read for an image html tag in an aria-live region.

Actual result

The alt text for an image html tag is not read in an aria-live region.

Example

In the example above, I expect the alt tag and div content in the aria-live region to be read after the button is clicked. -> "this is my alt text" "this is my div message"

The actual result only reads the div content in the aria-live region after the button is clicked. -> "this is my div message"
