Blocked autofocusing on a form control in a cross-origin subframe.

Hi:
I installed the release 2.1698-vsc1.41.1, and I use this command and set a password to start it:
```
code-server --host 0.0.0.0 --port 8082
```
this is ok to run.
But when i put it in iframe, when send the password will show this error on browser:
```
Blocked autofocusing on a form control in a cross-origin subframe.
```
This seems to be a cross-domain issue，but I can't found any setting to fix it.
If you has any idea, please tell me.
thanks you.
