Subject of the issue

The data attributes are ignored during adding new widgets through the addWidget function with specified coordinates.

Your environment

• gridstack version: 1.1.1
• browsers: any

Steps to reproduce

https://jsfiddle.net/Alexander_Sokolov/tu03kbgv/24/

• initialize the Grid with column=4
• prepare the widget HTML with an attribute data-gs-width="3"
• use the addWidget function to add new widget to the grid container with x and y coordinates:
  grid.addWidget(htmlElement, 0, 0);

Expected behaviour

The widget width is initialized from the HTML attribute (like it was in v0.4)

Actual behaviour

The data-gs-width attribute is ignored
