Example URL:
https://www.w3schools.com/tags/att_lang.asp

Steps to reproduce the problem:
1. Install and start up JAWS
2. Open a website with mixed-language content in IE11 and Chrome. https://www.w3schools.com/tags/att_lang.asp should be fine.
3. IE11 and JAWS will switch the read-aloud to the second language. Chrome and JAWS will not switch to the second language. For example, Chrome and JAWS will read any English-with-French content fully in English.

What is the expected behavior?
Given that we recommend Chrome for its accessibility, and a lot of our online languages courses have content that runs best using Chrome, it is disappointing that JAWS isn't able to pick up the secondary language mark-up in the same way it can from IE11.

This is of course assuming that the issue is with the Browser, rather than JAWS. It is assumed because the behaviour seems to be browser-dependent, when the browser is effectively the middleware.

What went wrong?
Secondary language mark-up does not seem to be detected for JAWS when Chrome is used.
