fix(Modal): no focus-wrap for "window lost focus" condition (#1268)
fix(Modal): no focus-wrap for "window lost focus" condition (#1268)

As focus-wrap behavior is for handling focus on an element outside modal.

IE11 behaves as though window lost focus when focus goes onto `<select>`,
which causes an adverse effect if such `<select>` is in a modal.

Fixes #1257.
