@MultipleOpen annotation not working

Hi Jmix team,

My system is currently using Tabbed-mode add-on and I want to prevent multiple instances of the same screen to be opened at the same time. I came across the @MultipleOpen annotation on the Jmix Documentation which is said to be false by default but I still can open multiple screens simultaneosly.

Have tried to set @MultipleOpen(value = false) as well but it didnt work as intended. After that I tried setting it in the application.properties file using jmix.tabmod.multiple-open=false but it did not work too.

Could you advise me on how to properly utilize this attribute to prevent multiple instances of the same screen opening?

P.S. The jmix.tabmod.multiple-open is false by default, but the annotation @MultipleOpen is true by default so its a little confusing too whether is it true/false by default.

Best regards,
Wei Jian.
