Better fix should take into account native xwiki suggest widget and works for both administration and patient form.
Currently, dismissing the Phenotype Search & Suggest dialog is only possible by only clicking the "hide suggestion" links at the top and bottom corners of the dialog.
It should instead behave like a proper modal, and be dismissed when any other part of the page is clicked (i.e. the dialog looses focus). When clicking back on the search box, the dialog should pop back up (it doesn't now). This will move Phenotips closer to being well-behaved on mobile, as well as improve the UI/UX.
