iOS: Button inside ScrollViewer inside Button Click issue

[ramarinkahua]

Current behavior

In iOS only (Android & Windows are okay), I have a setup where a button is inside a ScrollViewer, which in turn is inside another button:
Outer Button
--> ScrollViewer
------> TextBlock
------> Inner Button

When I click in an empty area, the outer button receives the click, but if I click on an inner TextBlock (or any control), it blocks the click. However, if I remove the inner button, the TextBlock no longer blocks the clicks from reaching the outer button.

Expected behavior

The outer button should keep receiving click events even when clicking on the TextBlock with the presence of the inner button beside it.

How to reproduce it (as minimally and precisely as possible)

Run the minimal repro project, click on 'CLICK HERE', notice that the console does not print '>> Main button clicked' (or hit breakpoint), but if you click on an empty area then the message is printed. However, if you comment out the button 'PART_RemoveButton' and rerun the project, then tapping on 'CLICK HERE' does cause the outer button to receive the click event and print the message.

Minimal repro project:
UnoApp3.zip

Workaround

Remove inner button 'PART_RemoveButton'
