When viewing a deeply nested path, there may be very little of the PathBreadcrumbbar itself visible to double-click on. This solves that by allowing double-clicks on its segment buttons to behave the same. (With the caveat that it first selects the double-clicked segment.) In order to make this work, `on_double_click` now takes the modifiers instead of the MouseEvent. In this case we don't use it so that's fine, but maybe we should make all mouse callbacks consistently take the MouseEvent& as a parameter.
