Steps to reproduce the problem:
1. Open a page in a non-local locale ( e.g. https://support.google.com/?hl=es or https://support.google.com/?hl=it if your locale is en-US )
2. The Translate this page? popover automatically displays in the top right
3. Keyboard input & shortcuts are now nonfunctional until the popover is manually dismissed. Try:
 - Pressing tab to switch between page elements, e.g, to move to the support search box to start searching (Nothing happens)
 - Pressing Cmd-F to activate Find (The Find search box displays behind the popover but you cannot type into it)
 - Pressing Cmd-L to activate the URL bar (The URL is highlighted but you cannot type into it)
 - Pressing Cmd-T to open a new tab (A new tab opens but you cannot type into the url bar)

What is the expected behavior?
When the Translate this page? popover is displayed, keyboard input such as shortcuts (Tab to move foucus, Cmd-F to find, Cmd-L to move focus to URL bar, Cmd-T for new tab, etc.) should function as expected.

What went wrong?
Keyboard input is nonfunctional while the Translate this Page popover is displayed.

Did this work before? Yes
