In Modal Dialog, RadListView swipe action causes random animation on list view items

[triple-j-95]

Environment

• CLI: 6.5.0
• Cross-platform modules: n/a
• Android Runtime: Not tested
• iOS Runtime: 6.5.0
• Plugin(s): n/a
• iPhone X iOS 13.3.1

Describe the bug

Swiping an item of RadListView on a modal dialog view causes multiple list view items to randomly animate.

• all items redraw themselves as if they were re-appearing with zoom effect from left corner (often happens in emulator)
• in addition to the item you swiped, one or more items rapidly move left to right multiple times as if they were shaken (both in emulator and physical device)
• swipe view may or may not appear even if main view is moved to left or right

If you swipe an item very carefully and slowly, while trying not to scrolling the list view or pulling down the modal view, then sometimes it works as expected.

To Reproduce

• Use sample project https://play.nativescript.org/?template=play-ng&id=hQiGvF&v=11
• Swipe an item in normal speed and
• Swipe an item little faster and
• Swipe an item slowly while observing other items starting to shake, see multiple items are left opened,

Expected behavior

Only item that is swiped, should move and swipe view must appear.

Additional context

@jon-jj it looks like an issue related to when creating a modal which is not fullscreen so I will mark this one as a bug.

Note that until recently iOS guidelines were that you could only have a modal page that is fullscreen. Setting fullscreen to true (which is also the default value) is resolving the issue.

let options = {
    context: {},
    fullscreen: true, // Here
    viewContainerRef: this._vcRef
};

Thanks NickIliev for the info.
I will temporarily use the fullscreen option instead.

Please any plans to resolve this ?
