Setup a IgxGrid component with:

• Set the grid data() signal . Data is a computed array. One property is the isSelected state of the row.
• One column is „isSelected“
• Sort the column isSelected so that the checked/selected rows are at the top
• Select a couple of rows by clicking on the checkbox.
• Start deselecting rows from the top.

Actual Result

The deselected row jumps somewhere else in the grid. The next selected row takes its place, but the isSelected checkbox is unchecked.

Expected Result

The custom igxRowSelector Template is refreshed and is in sync with the selected state of the row.
