Model-viewer: QuickLook on iOS Chrome does not work with .reality files, even with correct Content-Type Headers

[hybridherbst]

Description

A similar issue came up in #534, however, it seems that this time Chrome actually has an issue.
QuickLook supports both .usdz files (model/vnd.usdz+zip) and .reality files (model/vnd.reality). However, even with QuickLook chrome integration enabled, only .usdz files properly display in AR, .reality files always get downloaded (they work fine in Safari).

Expected: .reality opens in QuickLook in iOS Chrome when pressing AR button
Actual: .reality is downloaded in iOS Chrome when pressing AR button

@soraryu thanks for catching this. This may, in fact, be considered a feature request by the Chrome team (just speculating). IIRC they had to manually implement support for .usdz, so it is likely that they would have to do the same for .reality.

My recommendation would be to file a bug at https://crbug.com. If you do, I will reach out to some folks I know on the iOS Chrome team and see what they have to say 👍

Thanks for forwarding this!

Hello. Any news on .reality support in model-viewer?

[cdata]

This bug is about .reality file issues in iOS Chrome. At this time, I do not know of a reason why .reality files would fail in iOS Safari. @DA-NDI Can you confirm that .reality files fail with <model-viewer> in iOS Safari (not Chrome)?

Quick update: just got a notification that the bug is fixed in Chrome, so hopefully at some point in the future this will work properly.

Seems this will release in Chrome 85, already in Canary.
