Hi,

I'm seeing something strange when the suggestions appear right on top of a WInPlaceEdit. It appears the suggestions 'jump' a few pixels up when clicking, and thereby make me select the wrong suggestion.

I'll attach 2 screenshots to clarify the issue. On both screenshots I had my mouse pointer on the lower end of the 'testa1' suggestion. I then pressed 'Print Screen' (without clicking). As you can see in the screenshot of chrome, I'm actually hovering over 'testa2' instead of 'testa1', because the suggestionbox has moved up the screen. On Firefox the jump hasn't happened yet. You can also see this 'jump' in action on chrome and firefox by hovering over a suggestion and then KEEPING your left mouse button PRESSED IN. You will not select anything, but you will see the 'jump'.

I'll attach the source code to reproduce the issue. To reproduce this: MAKE SURE YOUR SUGGESTIONS ARE RIGHT ON TOP OF THE WInPlaceEdit! I did this by enabling the 'developer tools' on chrome, or enabling the 'firebug' extension on firefox, both on the bottom of the screen.

You will not be able to reproduce this if the suggestions appear below the WInPlaceEdit, or floating free at the top of the screen.

    testpopup->setModel(model);
    testpopup->activated().connect(bind(&HelloApplication::line_edit_changed, this, _1, edit, testpopup));
    edit->setButtonsEnabled(false);
    testpopup->forEdit(edit->lineEdit(), WSuggestionPopup::PopupTrigger::DropDownIcon | WSuggestionPopup::PopupTrigger::Editing);
    testpopup->setFilterLength(0);
    testpopup->addSuggestion("testa1", "testb1");
    testpopup->addSuggestion("testa2", "testb2");
    testpopup->addSuggestion("testa3", "testb3");
    testpopup->addSuggestion("testa4", "testb4");
    testpopup->addSuggestion("testa5", "testb5");
    root()->addWidget(cont);

void HelloApplication::line_edit_changed(int selected, WInPlaceEdit *edit, WSuggestionPopup *popup)
{
   std::string new_data__ = (asString(popup->model()->data(selected, Wt::DisplayRole))).toUTF8();
   cout << "\nnew data: " << new_data__ << "\n";
   edit->textWidget()->setText(new_data__);
   edit->lineEdit()->setText(new_data__);
}

FYI: I'm using version 3.1.11

Thanx for your great framework!
