• fix: avoid template string/literals

• fix (mobile): hide keyboard when scroll suggestions (#15)

Autocomplete suggestions will only be updated when a new response came from the source method.
This will prevent old responses (when source method is async) from messing up the result items

Instead of using document.body to insert autocomplete element, use the target's parent and then, if the target is inside an element with position [absolute, fixed or relative], use relative values to adjust element position
