Enterprise: Accordion: Header stays selected in Safari

[shane-infor]

Describe the bug
Accordion header stays selected even if the user click on other panel in Safari only.

To Reproduce
Steps to reproduce the behavior:

1. Go to http://latest-enterprise.demo.design.infor.com/components/accordion/example-accordion-panels.html in Safari 12.
2. Click on the Accordion panel header.
3. Click on another Accordion panel header from the same Accordion.

Expected behavior
When the user click on panel, rest of the panel should loose the focus.

Version

• ids-enterprise-ng: 6 (latest)

Screenshots

Platform

• Device: Mac
• OS Version: Latest
• Browser Name: Safari
• Browser Version: 12.1

Additional context
It seems that when a user click on the panel, it is not removing the is-focus from other panels.

@shane-infor I moved this issue to the regular Enterprise repo, since this is reproducible in EP.

@tmcconechy I'm going to fix this one in my current batch of Accordion/App Menu stuff for v4.22.x
