Provide an easy way to open multiple items from the history dialog
Epiphany version 3.33.4-29-gf6bb1bce with WebKitGTK 2.25.2 on FreeBSD 12.0
In the old history dialog, it is easy to open multiple items. You can select multiple items with Shift-↑ and Shift-↓, or left clicks while holding Shift or Ctrl. After items are selected, you just click the open button at the buttom of the dialog to open all of them.
In the new history dialog, Shift-↑ and Shift-↓ no longer works. Left clicks with Shift and Ctrl still work, but there is no button to open selected items. Right clicking on the selected item resets the selection to one item, which is probably not what a user wants. The only way I know to open multiple items is to right click while holding Ctrl, which is unlikely to be discovered by users if there is no hint.
