+ // [JAL-3226] problem that JavaScript (or Java) may consolidate multiple
+ // repaint() requests in unpredictable ways. In this case, the issue was
+ // that in response to a CTRL-C/CTRL-V paste request, in Java a fast
+ // repaint request preceded two full requests, thus resulting
+ // in a full request for paint. In constrast, in JavaScript, the three
+ // requests were bundled together into one, so the fastPaint flag was
+ // still present for the second and third request.
+ //
+ // This resulted in incomplete painting.
+ //
+ // The solution was to set seqCanvas.fastPaint and idCanvas.fastPaint false
+ // in PaintRefresher when the target to be painted is one of those two
+ // components.
