            Bug ID: 204735
           Summary: REGRESSION(2.27): [GTK] Tooltips from previous page
                    shown on new page
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mcatanzaro at gnome.org

We're having trouble with tooltips from a previously-loaded webpage being displayed for a new unrelated web page after loading a new page in the web view. It's easy to reproduce using the Epiphany overview. Hover your mouse cursor over any of the overview items to display a tooltip. Then, using the keyboard, Ctrl+L to focus the address bar, type in any web address, e.g. https://www.gnome.org, and hit Enter to load the page.

With 2.26, the tooltip appears on the new page, but only until the mouse is moved. As soon as the mouse is moved, the tooltip disappears and never comes back.

With 2.27.3, the tooltip has developed aggressive zombie tendencies. It just doesn't want to die ��. Move the mouse, it will come back again and again. To avoid the bug, you can hover over some element of the new web page that displays a tooltip and our zombie tooltip will finally die. For example, using https://www.gnome.org as our second page load, you can hover over the GNOME foot in the top-left to get rid of the zombie tooltip. I remember this when testing 2.27.2 and maybe also 2.27.1, so it's an earlier regression. I just never managed to figure out how to reproduce it until now.
