Notes

  • 1

    Partial. Not supported with Hotmail/Outlook accounts.

  • 2

    Partial. The popovertarget attribute is supported, but the popover attribute and the dialog element are not.

  • 3

    Buggy. A button with just an image inside will trigger an image zoom rather than the popover.

  • 4

    Partial. Does not work with command/commandfor attributes only with popovertarget/popovertargetaction
