问题
After multiple elemens are selected and dragged, some of them are no more resizable: resize icon disappear from right corner.
Resizable icon remains in old place and does not move which moved elements.
To reproduce, run code below, select all elements using lasso and drag selected elements. After that resize icon disappers from random elements and those elements are no more draggable.
How to fix this ?
i tried to fix this by adding
$(".designer-verticalline, .designer-rectangle, .designer-field, .designer-image").resizable();
to end of drag() methos but problem persists

The problem is that the resizable icons are selectable as well, so when you include them in the lasso, they are selected and their top and left are changed when you drag.
Selectable has a filter option that allows to specify which elements should be selectable. By setting it to '.designer-field' it should solve the problem.
$(".designer-panel-body").selectable({
filter: '.designer-field'
});
