ListGrid messed up when using autoFitValues:true and canFreezeFields: true

I've found an issue with the ListGrid when using both autoFitValues: true and canFreezeFields: true.

To see the problem, check out the following showcase example:

Edit the code and add canFreezeFields: true. Then click the Try it button. Switch to the ListGrid View and freeze the Country column.

Notice that Country fields resize to their default height while the Background fields remain large, so the rows are no longer complete rows.
