Relative layout content disappeared when Relative layout has the border with border stroke element.

[NanthiniMahalingam]

Root cause

• When we set the stroke shape for border, visual element stroke shape is added to the border. Here, handler does not set to the stroke shape element.
• Therefore, IsPlatformEnabled property is set to false for stroke shape of visual element.
• It caused the content disappeared due to update children calculation does not invoked.

Description of changes

• Skipped IsPlatformEnabled condition checking for shape when adding a stroke shape inside the border because the handler for the stroke shape element was not set.

Validated the behaviour in the following platforms

• Android
• Windows
• iOS
• Mac

Fixes #23934

Hi @PureWeen

Where is this check happening?

• Therefore, IsPlatformEnabled property is set to false for stroke shape of visual element.

I'm wondering if we can resolve this issue without needing to call ToPlatform on the shapeviews

We have modified the fix without the need to call the ToPlatform method on the shape view. Could you please verify once?

Only happens with RelativeLayout or with all the legacy layouts?
