RFR: 8346234: javax/swing/text/DefaultEditorKit/4278839/bug4278839.java still fails in CI

[Prasanta Sadhukhan]

Test seem to fail in CI due to caret position not in expected position after pressing VK_RIGHT/VK_LEFT.
Added some log which shows the same


passed1 moveCaret1 true
passed2 moveCaret5 true
passed3 moveCaret8 true
passed4 moveCaret9 false
passed5 moveCaret13 false
passed6 moveCaret16 false
passed7 moveCaret17 false


Added some delay for this slow system..Tested to pass in several systems..link in JBS
