Is there a convenient way to show backdrop between 2 popups in the scenario where you open a popup on/from a popup? By default, it doesn’t work.
Well, this is not really a good practice and won’t work by default
You need some custom workaround to make it work
As the simplest one, you can pass
backdrop: false to the second popup and
closeByBackdropClick:false parameter to both popups. So there will be still first popup’s backdrop used for second one too, and clicking on it won’t close popups
