I've moved the google translate widget to a separate file. Wasn't able to come up with a reduced test case just yet, but noticed a couple things.

The pop up list of languages is being displayed in an iframe when I click/press Enter on the drop down. The keyboard trap happens only after attempting to select a language for a second time. After selecting a language for the first time the following method is used to hide the iframe: 

```
    function Q(a, b) {
        a.style.display = b ? "" : q
    }
```
so the iframe gets `display:none`.  I change the code to alter visibility instead of display, e.g. `a.style.visibility = b ? '' : 'hidden'` then the keyboard trap doesn't happen. 

So perhaps it has something to do with the fact that the iframe is hidden with `display:none`. I'll continue to investigate this and try to come up with a reduced case
