NavigationItem (store) support for longer names

[MajorXAML]

Is it possible to add support for longer names? i'm not sure how this is done in the localized ms store, maybe via running text on mouseover?

Hi, in the Microsoft Store, it is done by shrinking the text. That is not an ideal solution, however, because the name may be harder to read.

Could we make Height and Width of the Pane item following its content?
