I have experienced this and you don't need to load your vault. I just right click on the field, go to the lastpass entry on the menu and do copy username, paste then the same for password.
It takes a few seconds longer, but still works. Also, saving the details of a site is done automatically. All you lose here is a bit of ease of use. A visit to your vault and a few clicks makes the site a new permanent entry.
