RAD Studio 12 debugger does not fall into interface methods when pressing F7.

The debugger does not fall into interface methods.
In RAD Studio 12, when I press F7, the debugger does not fall into interface methods. RAD Studio 10.4 falls normally.

For example, if you set a breakpoint on line 
FCaptured.MouseClick(Button, Shift, P.X, P.Y);
Or
Obj.MouseClick(Button, Shift, P.X, P.Y);
In the method
procedure TCommonCustomForm.MouseUp(Button: TMouseButton; Shift: TShiftState; AFormX, AFormY: Single; DoClick: Boolean = True);

 

  Obj is IControl; and FCaptured is IControl;

then the RAD Studio 12 debugger on F7 does not go to debugging the method
procedure TControl.MouseClick(Button: TMouseButton; Shift: TShiftState; X, Y: Single);

I can't understand if this is a feature or a bug or a setting.

 

Addition:
It seems that the problem only occurs in the Target Platform mode – Windows 64-bit.

In Windows 32-bit mode, the debugger falls into the method.

I can confirm this. You should report it on QP.

Same here. Works in 32-bit, does not work in 64-bit.
