How can we sort the projects of in row grouping by priority in grid?

[EPM Solutions]

Hello Team,

We want to sort Projects by their Priority in descending order in row grouping, dynamically.

We need to sort it in on page load and on some different instances (dynamically).

One Case it is working but another one case it is working (sorting record as required).

Please check below plunkr and give a solution (sorting Projects by their Priority in descending order in row grouping keeping portfolio-record on top).

Note: >records of .constructive (.Budget/portfolio) should always need in top (sometimes - sorting record as Priority descending, it is coming down.)
