This relates to https://github.com/infor-design/design-system/issues/294 once we change this colors on a new issue when thats decided we should also test and fix this for IE with the new colors. This bug occurred when this component was created in 4.14 and was'nt noticed until now.
Just curious - do we know why the current colors (background-color: rgba(213, 246, 192, 0.4) for example) aren't showing on IE? Is it because of the opacity? If that's the case, going "solid" in the proposed solution would fix this bug.
@kayiuho I think its just because we use css RGBA there which is not supported on IE. We should convert these to HEX or use the HEX OR RGB with an actually css opacity. So, coding error.
We still need to make the changes here
QA Passed. Will move to Done. Thanks!
Tested in: http://master-enterprise.demo.design.infor.com/components/notification/example-index.html#
Moving to Failed QA, issue still exists on http://4180-beta0-enterprise.demo.design.infor.com/components/notification/example-index.html#
Further debugging:

Which happens because of this in the JS code:

Because we do this in the JS:
this.notificationEl.classList.add('notification', this.settings.type);
