How to prevent hide popup when click in popup's children component such as richselect item?

I saw webix_debug@2.2, you remove _clever_block, why?

Previous solution with _clever_block and 100ms delay was not stable. In case of slow code in onshow handler popup can insta-close just after opening.

Do you have some problem with the new codebase ?

Yes, please check this snippet

Yep, it seems we have a regression.
I have sent you a private message, please check it.

Issue fixed, thanks!

Fix for the nested popups was released as part of Webix 2.2.1
