If you have a datable with a checkbox column, the control gets unchecked if you resize the datatable.
To reproduce:
Select any number of rows
Resize the browser window.
You will notice the previously checked rows and now unchecked.
I noticed this after adding a confirmation sweetalert to the grid. The sweetalert appears to slightly change the page size which causes the m-datatable--on-layout-updated to fire.

Thanks for your feedback. We will fix the checkbox issue on resize.
