Currently, when using WWidget::positionAt(), the positioned widget will be reparented in order to have it follow the the widget it is positioned next to when the new parent is being scrolled. This can be a problem when the widget is a popup, as it can be added to a widget that has not enough space to show it correctly, while it could easily be completely visible if it was showed at the top level (but would then not follow the widget it is next too when scrolling).

This could be solved by using CSS anchor, which allows to define the position of an element relative to another element on the page.
