[table] expansion state is lost when data is updated

[DRiFTy17]

Describe the bug:
When using the expand row functionality in the table, if the data is updated (or the render() method is called) while a row is expanded the table will re-render completely and it won't leave the row expanded.

To Reproduce:
Steps to reproduce the behavior:

1. Expand a row in the table
2. Either reset the data property, sort a column, filter a column... etc. (anything that causes a re-render of the data) and the table will re-render completely without leaving the existing expanded rows open.

Expected behavior:
All rows that are currently expanded should retain their expansion state when the table is re-rendered.
