JAWS Screen reader repeats values

[JRomero0613]

Test device: PC Laptop

Operating System: Windows 10 v. 1803

Browser: Firefox v. 60.0.2

Problem description: For phetsims/qa#130 when using the JAWS screen reader the screen reader will repeat both current, and non-current slider values.

Steps to reproduce:

1. Using keynav navigate to a slider and adjust it by holding down an arrow key (this bug is more noticeable when holding the arrow keys down)
2. The screen reader will read out a value multiple times (around 5 or 6), the value might be one in between where the slider started and ended or it could be the current correct value. I have not been able to determine why it reads out certain values and not others.

@jessegreenberg @terracoda is this a known issue?

[jessegreenberg]

Looks very familiar, checking.

This is identical to this one: phetsims/john-travoltage#227

We determined it was a JAWS bugs that happens on all sliders, like this one: https://jsfiddle.net/1j1y3s8p/

I am going to add this bug to the new "known bug list" and close this issue. Here is the list for future reference, and Ill add the link to it in the QA test checklists. https://docs.google.com/document/d/1518zv6F0odExFsodShZxwTmWNQk3civuNwtQUR-rEBs/edit
