Bug fix : Hovering now doesn't depends on search filters anymore + min window size

[Pythyu]

Fix the issue #31

As the title say, hovering now should work even when the item hovered over doesn't match the search filters

Fix now the issue #42 as well by reducing the minimum size the window can have

[Pythyu]

Added a fix of the hovering issue of #39

Basically the condition on item seems to not be working all the time by doing List.Contains(item) so replaced it by a check of the item ID

Thanks a lot to Emberblink for helping out to debug this
