Cannot seem to surface passkeys in search

I can easily find items with TOTP codes attached by searching for "one-time password" since that's what 1Password names the field. However, this doesn't seem to work for passkeys. Searching for "passkey" (the displayed name of the passkey field) doesn't surface all items with a passkey attached, only a few that have the word "passkey" in the saved URL.
