When we are opening a menu dropdown in IE jaws it is announcing the text of the heading which is present in another div. Sample app has been deployed at following location -https://jawsaccessibility.herokuapp.com/index.html
Steps to replicate
Output - "Nam non metus diam........" text will be announced with dropdown text.
Expected - only dropdown text should have been announced

This is due to an issue with how IE represents elements in the accessibility tree. When an element has a tabindex then it is included in the accessibility tree and the accessible name for that element is the child text, unless there is some other source for the accessible name provided. In the test case is presented as a grouping object in the accessibility tree with an accessible name of "Nam non metus diam. Mauris vehicula ac lectus eu pharetra" and is announced when the dropdown button receives focus.
Try adding aria-label="" (empty label) to the div. This provides an alternative 'null' label for the div and resolves the problem.
