Calculator: The custom titlebar isn't correctly displayed on Windows 10X

[rudyhuyn]

Describe the bug
Windows 10X preview has currently an issue with custom titlebars (CoreApplicationViewTitleBar returns Height = 0px and IsVisible = Collapsed instead of 32px and True)

Expected behavior

A future preview of Windows 10X will fix this problem, but in the meantime, we should display the title bar correctly on Windows 10X.

Requested Assignment
If possible, I would like to fix this.

It would be useful if you could detail some of these kinds of considerations that will need to be made for designing apps for Windows 10X. I know you said this Core Application TitleBar thing is a bug, but it may be helpful to other app design teams which use custom titlebars.

Especially if we can hopefully encourage developers to extend acrylic into the title bar, and avoid duplicate Title Bars

@mdtauk: the bug related to the titlebar will be fixed soon, way ahead of the public release for 10X and applications using a custom titlebar won't be impacted. The only reason we need this temporary patch is because we are actively working on dual-screen support and we want to start testing our UI.

We are learning a lot with our own applications, we have built many useful controls and helpers that we will share with the community.

Especially if we can hopefully encourage developers to extend acrylic into the title bar, and avoid duplicate Title Bars.

This is probably something we can do via the Community Toolkit, don't hesitate to suggest this idea here: https://github.com/windows-toolkit/WindowsCommunityToolkit
