Row Expander will often become "detatched" from record.

[conn.finn]

Hello,

I'm running into an issue where the row expander is getting detached and stuck from the record as shown in the picture below:

Reproduction Steps:

1. open Row Expander Span Regions demo
2. Edit a cell, such as the "Age" cell.
3. Without saving or cancelling, sort by ID so that the order is reversed
4. Do this 3 times.

Result: you will see the expanded section be "floating". Pressing cancel will not remove it.

Other ways to reproduce:

• If the grid has a group applied, closing the group while the expander is opened will detatch it.
• If the expander is open and the user scrolls far enough into another group, it will detatch the editor. Perhaps happens when DOM node is re-used for record with different grouping.
