Strange Bug in FormModal with MenuItem and VCLStyles

[luapfr]

VCL Styles Bug Menu Modal.zip
I searched on Google but I didn't find anything about it is a very strange situation.

the Problem happens when calling a FormModal by a MenuItem
when closing this form the entire Project is Closed together.

Run this attached demo and call Forms -> Form2
when closing Form2 the entire application will be hidden together.

Delphi 10.2.3 it is OK
I took out Vcl.Styles.Fixes it did not compile.
closing form2 form1 stay it is ok

I put it back Vcl.Styles.Fixes and it is OK
no problems

So the Problem is in Delphi 10.4
