Fix: ULS popup moves to sidebar if opened from ime menu

Issues fixed:
Incorrect position of ULS when accessed from more languages button
of input/display settings, when language settings opened from ime
menu.

Arrow(callout) appearing for ULS when opened from more languages
button of input/display settings, when language settings opened from ime
menu.

Used a class 'callout' to mark whether windows need callout arrow or not.
