Bug: SSH agent cannot be used when connected via Remote Desktop

I'm using the 1Password 8 Windows beta with the SSH agent enabled and configured with a couple SSH keys. When functioning normally, 1Password asks for a Windows Hello PIN to unlock my SSH keys, and everything works fine.

However, when connected to my PC via Microsoft Remote Desktop (with the official client on macOS, if that makes a difference), I cannot unlock my SSH key. 1Password asks for my master password, which I provide, but the SSH agent refuses the operation.

With git, for example:

```
sign_and_send_pubkey: signing failed: agent refused operation
sign_and_send_pubkey: signing failed: agent refused operation
mailto:git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
