    xdg-shell/popup: Reset 'dismissed-by-client' state when remapping
    
    A popup surface can be remapped multiple times using the same
    wl_surface, if a new xdg_popup object is created. To properly handle
    this, we need to reset the 'dismissed_by_client' boolean to false, as
    otherwise we won't allow new buffer commits.
