Describe the bug / provide steps to reproduce it

1. Click on "Recent Projects
2. Click "Connect..."
3. Click "+ New Server
4. Enter the server name in the "Name" input
5. Click "Create"
6. Notice that the "Name" field is now disabled, but still has focus and contains the cursor at the last position.

The expected behaviour would be

• The input loses focus / the cursor disappears.
• The user can't focus the "Name" input while it's disabled.

In addition, if the input still has focus, I can submit the new server form by pressing Enter, which creates as many server configs as I submit the form.
