When will a "quick view" for .HEIC images be available?

Many of our team members have iPhones and the new photo format apple is pushing is .HEIC.

When we upload their photos to the attachment line they are not able to be clicked on and viewed the way a JPEG is. Seeing that this a new direction in photo formatting, when can we expect a "quick view" the way we have with JPEG images?

I have attached an screenshot of what I mean by "quick view"

And before anyone says it, we have changed the format in their phone cameras to save in JPEG but it keeps getting changed back. Possibly due to software updates, or some other reason that we cannot predict.
