OwnerModifiedTests was not properly spawning from the non-session owner client (it was spawning with ownership on the session owner side). NetworkVariableCollectionTests is showing an issue with changes for only the host instance and only within the TestDictionaryCollections (has to do with trying to add and then reverting vs the tracked changes).

Are you sure you linked the correct PR as the regression root? (you linked CoreCLR update) |

Yeah it was supposed to be #3664... |
Fixed the issue in the `TestDictionaryCollections` test where clients that did not have the initial added target changes for server changes when running a host. Now, upon clients spawning players locally on the clients, the server write dictionary that is already populated by the host will have the added target changes injected during spawn to assure the changes match. (This is only for this specific test when running the host `TestFixture` pass.

…ost-spawn. (#3878) * fix Fixing the issue with the missing `OnSpawned` override within `NetworkVariable`. * test Adding a general test for scenarios like this one. * update Adding changelog entry. * style Adding comments for clarity of what `OnSpawned` and the call to `PostNetworkVariableWrite` is for. Removing trailing whitespaces. * refactor Just apply the changes to the NetworkVariable instance and not all NetworkVariables of the NetworkBehaviour. * style correcting the comment. * fix Very similar to NetworkList (we might collapse the OnSpawned logic into NetworkVariableBase. * test-fix OwnerModifiedTests was not properly spawning from the non-session owner client (it was spawning with ownership on the session owner side).
