Don't change the focsued frame when target node is null.

[Title] Don't change the focsued frame when target node is null.
[Issue#] N_SE-39321
[Problem] The focus of IME is moved after panning.
[Cause] The focused frame is changed whenever panning starts,
        even though the touched node is not scrollabled.
[Solution] Don't change the focused frame when the pressed node is
           not scrollable.
