+Subject: [PATCH] Handle process parent changes in ProcessDataModel
+
+When the PPID of a process changes, it moves around in the model, changing the
+layout. This needs to be announced properly, otherwise users of the model get
+confused, leading to weird behaviour and crashes.
+
+The added code is pretty much a direct copy from ProcessModel.
+
+BUG: 446534
+
+
+(cherry picked from commit a0d70929a1b5e38bd8bf61e1895321124acf03a7)
