When doing a selection where the end position x is > to the start position x, this is interpreted as a "swipe towards right" gesture, and it moves to the previous page. The selection pop-up menu allears on the new page, whereas the selection is where it should be, on the page that just disappeared. Tested in R2 testapp, develop, and a R2-based app.

• Page with the pop-up (incorrect)
