IDistributedLockProvider for Redis won't acquire lock when using multiple databases

[omexus]

Given:

        var connectionPoolManager = services.BuildServiceProvider().GetService<IRedisConnectionPoolManager>()
                                    ?? new RedisConnectionPoolManager(connectionConfiguration);
        var dbs = connectionPoolManager.GetConnections().Select(c => c.GetDatabase());

This wont work (handle returns null always - no exception thrown):
services.AddSingleton<IDistributedLockProvider>(_ => new RedisDistributedSynchronizationProvider(dbs);
But this does work:

services.AddSingleton<IDistributedLockProvider>(_ => new RedisDistributedSynchronizationProvider(dbs.First()));

Cool library btw - Thanks!

@omexus in this scenario are the different IDatabase objects pointing to separate keyspaces/distinct servers? If they are different views to the same DB, it won't work.
