-connect-fail-fast=false doesn't work

Neither on Windows 11 nor with the Docker image.

```shell
grpcui --version
grpcui v1.4.1
```

```shell
grpcui --open-browser=false -plaintext -connect-fail-fast=false -connect-timeout=1 127.0.0.1:9000
Failed to dial target host "127.0.0.1:9000": dial tcp 127.0.0.1:9000: connectex: No connection could be made because the target machine actively refused it.

```

As soon as the gRPC server is running:

```shell
grpcui --open-browser=false -plaintext -connect-fail-fast=false -connect-timeout=1 127.0.0.1:9000
gRPC Web UI available at http://127.0.0.1:13540/
```
