STR (with the NVDA screen reader):
1. Start NVDA and Firefox.
2. Open the Web Console with control+shift+k.
3. Ensure NVDA's speak typed characters function is off by pressing NVDA+2 until it reports as off.
4. Type "z" (no quotes).
Expected: NVDA shouldn't say anything.
Actual: NVDA says "z".

The input textarea (class: jsterm-input-node) is now inside the element with the aria-live attribute (id: output-container), so it inherits aria-live. Previously, it was outside the aria-live element. This can be fixed by just setting aria-live="off" on the textarea.

I'm not exactly sure when this regressed, but it works as expected in Firefox 60.
This was probably caused by Bug 1425521 (which also mean we should have a test for that)

James, I'm trying to fix this, and I set the aria-live attribute to off on the .jsterm-input-container element.
It seems to propagate to the textareas since I can inspect them with the accessibility tool and see that "container-live" is "off".
I'd like to have a test for that so we don't regress anymore, but I can't find a way to check for this "container-live" attribute in js. Would you know how I can do that ?
Unfortunately, container-live is generated internally by the accessibility engine. As far as I know, there's no way to access that from js.
Okay, thanks. I guess I'll go with a function that walk up the dom tree until it finds an "aria-live" attribute and check it's off (or that there's no parent with  aria-live).
