JTable Does not properly repaint on calling fireTableRowsUpdated

ADDITIONAL SYSTEM INFORMATION :
Mac & Linux

A DESCRIPTION OF THE PROBLEM :
This code used to work in Java 7 & 8 but seems to be broken in Java 10 (and possibly 9). I've tested both on Linux and Mac and it is broken in both.

REGRESSION : Last worked in version 8u172

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run the the attached class ChainedModelTester.java


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
A window should pop up and the rows should be updated one by one and repaint (Java 8).
ACTUAL -
On Java 10, rows go blank and don't repaint unless clicked on.

CUSTOMER SUBMITTED WORKAROUND :
call fireTableDataChanged(), which although inefficient, does repaint everything.

FREQUENCY : always
