I initially misintepreted the meaning of the enum, assuming that it meant that the window should possibly be blocked. The user_gesture parameter in WebContentsDelegate::AddNewContents is actually doing this, while the popup disposition means that JavaScript requested the window to be opened without one of the standard decoration (i.e. status bar, menu bar, tool bar, etc.). Update the QtQuick API to reflect this, renaming the "isPopup" parameter to a more familiar "isUserInitiated". The popup disposition is named "dialog" to match the previous QWebPage::WebModalDialog enum.
