Dynamic linker error while starting Epiphany Tech Preview

Hi,

If you encounter the following error:

$ flatpak run org.gnome.Epiphany.Devel
epiphany: error while loading shared libraries: libhogweed.so.4: cannot 
open shared object file: No such file or directory

The problem is 
https://gitlab.gnome.org/GNOME/gnome-software/issues/760, GNOME 
Software has updated your runtime but not Epiphany itself. Workaround 
is simply:

$ flatpak update
