Hello, could you have a look please at 36 line of my snippet.
Webix dont change popup position if we select item first time. It`s so strange and i think what this bug cuz if we click on “send-email” button when list item was selected, popup successfully change position for click target.
https://snippet.webix.com/nutztio8
line 34: this.select(id);
after this command list is repainted, active node is removed from DOM and its position is out of view.
therefore when you use it as position reference in line 126, it became useless.
as a workaround, try to replace line 34 with this
webix.delay(this.select, this, [id]);
