SfDataGrid Memory Leak

While implementing the SfDataGrid control I have noticed that it causes a memory leak. It keeps a reference to the host page even after garbage collection.

I cannot attach the sample project directly to this ticket due to file size so please use the google drive link provided that will allow you to download the .zip folder.

Repo Steps
Open attached zip in VS2019 and select UWP as default platform Tap on Show Gauge Button Tap on X in top right corner Tap on "Force Collection" 3 times Take memory snapshot

Return test steps another 3 times.

Expected Result
0 instances of PosPage andchild pages retained in memory

Actual Result.
4 instances of PosPage and child pages retained

Thanks,

Liam
