LayoutSizeConstraint does not work in UWP

When I run the same app in win 32, the window resizes appropriately based on the content when the LayoutSizeConstraint is set to SetMinAndMaxSize

while running app there is a warning or error suggesting that there will be a problem
qt.winrtrunner.app: This plugin does not support propagateSizeHints()

I am unable to put here and example. Jira is reporting an error (Jira could not attach the file as there was a missing token. Please try attaching the file again.) while uploading files

I just created a new qt gui project, put there few elements, set the vertical layout and set the Layout size contraint.

Maybe it has to do somithing with other unexpected behaviour
When I do a qml app again a new project in qt creator. I set the size of the window
Window

{ width: 340 height: 880 visible: true title: qsTr("Hello World") }

It does not work, the size is actually 1202x780 r something like that on my fullHD screen. There is some bug with settings the size of the app window in uwp?
