[Bug] [UWP] First Entry gets focus if loaded inside ScrollView

[LakshmiNatarajan21]

Description

When the Entry control is loaded inside the ScrollView and tapping the empty space of the view, the First entry gets focus in the UWP platform.

I have found a workaround for this issue in the following discussion,
https://stackoverflow.com/questions/42064603/xamarin-forms-scrollview-click-always-sets-focus-on-first-item-of-child-grid

But, this workaround is broken from Xamarin.Forms Version 3.6.

The workaround resolves the issue in XF 3.5.

Steps to Reproduce

1. Run the sample in the UWP platform.
2. Click any entry control. Then click the empty space of the ScrollView.
3. First entry element gets focus.

Expected Behavior

Focus should be disabled for all entry items.

Actual Behavior

First entry gets focus.

Basic Information

The reported issue does not occur, when adding Entry inside Grid. Please see the video which reproduces the issue.

public class ScrollViewCustomRenderer : ScrollViewRenderer
   {
       protected override void OnElementChanged(ElementChangedEventArgs<ScrollView> e)
       {
           base.OnElementChanged(e);

           if (Control == null)
               return;

           Control.IsTabStop = true;
       }
   }

But, workaround broken from XF 3.5.

microsoft/microsoft-ui-xaml#597 (comment) - As discussed in this comment, Duplicating ScrollViewRenderer without IDontGetFocus interface also seems to work.

But, we have our own custom renderer and we cant implement the actual ScrollViewRenderer.

Does this mean we might see a fix for this bug in one of the upcoming previews?

[Suriman]

The current behavior does not make sense. Neither in UWP nor in mobile. If the behavior of other applications is observed, the correct one is not to scroll to the first element of the form.

Would it be possible to advance the implementation of this issue?

Any news about it? Does anyone know of any workarounds until it is officially fixed? I tried the solution that is proposed in the following link:
https://stackoverflow.com/questions/42064603/xamarin-forms-scrollview-click-always-sets-focus-on-first-item-of-child-grid
But no it works in the latest versions of Xamarin.Forms.

I have prepared a sample where the problem can be reproduced:

I have also prepared a video on how to reproduce the problem in the example.

The example is using Xamarin.Forms version 5.0.0.2083.
