Kendo-angular: Grid -> trackBy -> detail rebuild every time

[meriturva]

We are using a lot of Grid and MasterDetail features, we just have a case where we use (for performance reason) trackBy function.

What we have found is that detail is recreated also when we have trackBy function present.

See simple plunker here: https://stackblitz.com/edit/angular-4fqbbu
open a row detail and see console, you will note that the detail component' s constructor is called every time data is refreshed.

I think that if trackBy function is used, also detail row has to respect that? am i wrong?
Any workaround in case?

Should be fixed in the latest development version.
