Netcode for Entities: Ghost groups with dynamic buffer on child entity

This bug was encountered when using ghost groups, where the child entity has a dynamic buffer. In my case, the ghost groups and parent/child components are setup at runtime. The error shows in the console when the buffer exceeds a certain length (20 in my case). The error message is: "InvalidOperationException: writing snapshot dyanmicdata outside of memory history buffer memory boundary".

With the attached sample project, entering playmode is enough to see the error. I have tested this with netcode for entities versions 1.0.15 and 1.2.3.

Full error:
