TextArea ReadOnly and DropObject event odd behavior

I’m Working with Xojo 2021r1.1 (not sure what happens in older versions)
I stumbled upon an odd TextArea behavior.
When a TextArea is set as Read Only, Drag Enter, DropObject and all related events will not trigger on macOS but will fire up on Windows.

I’m not sure whether macOS or Windows is doing it as intended, I only know it inconsistent between the two.
