Hello Petr,

Thanks for raising this issue!

I reproduced on my side and have created a small project with the code you provided.

I will ask one of my colleagues to have a closer look.

Thanks again
Damien

@Damien_Urruty great, thanks for letting me know.
It was strange because after the first time I saw it this problem disappeared until I reloaded the project.
