Start by reproducing the JSON highlighting problem in Notepad++ v8.2.1 using the sample [1,2,3,4,true,false,null,"aaaa"] and the JSON highlighting style. Trace the JSON syntax-highlighting implementation from that behavior, then verify that numbers, booleans, null, and strings receive distinct colors without regressing object-name highlighting.
