Xamarin.forms: [UWP] fails to show context menu of a list view item

[FrankChen021]

Description

on UWP, context menu of a list view item cell won't be opened if the mouse is clicked outside any children controls of that cell

Steps to Reproduce

1. open the interactivityListView sample project provided by official xamarin-forms-samples
   

2. open the interactiveListViewCode.cs, add a button to the ViewCell. the picture below shows the code differences, the right part shows the code we added

1. run the UWP sample project

Expected Behavior

the APP shows as

the dotted rectangle shows size of a cell. it's supposed to show the context menu if the mouse is right clicked at ANY POSITION of this cell because the context menu is associated with this cell

Actual Behavior

unfortunately, only if we click in the areas of child controls in a cell (as the red rectangles shown below), the context menu would be showed. if the mouse is clicked in other position of that cell, there's is no context menu.

if HorizontalOptions of Label is set to FillAndExpand, the label expands to the whole cell, as the dotted rectangle shown below. So if we click in any position of this rectangle, the context menu DOES SHOW. but if we click in those red rectangles, it WON'T

It appears to occur when using the horizontal orientation on the layout.

[FrankChen021]

@pauldipietro whether it's horizontal orientation or vertical orientation makes no difference

why does the original sample project work? it definitely uses vertical orientation. but it works not because that. in vertical orientation, the default value of HorizontalOptions of controls is Fill, these control stretch to fill the layout horizontally. in most of case, the position where a mouse is clicked inside a cell is in a sub control, so the context menu shows. if you change value of HorizontalOptionsto Startor End, this problem would be easier to reproduce.
