Fix editor value being lost when window loses focus

Problem can be observed in 'test/Editor_more_widgets.html':
1. Click a cell in the "Select Store" column
2. Change the value in the select
3. Activate a different application (causing the browser to lose focus)

Result: the edited cell reverts to its previous value and Grid.js throws
an error in Grid#cell()

This change fixes the focus event handling for this scenario.
