Re: [Geary] Theme in 3.34

[Axel Ulrich <ulrich axel gmail com>]

Thank you. I had never thought about the theme aspect in the context of 
the flatpak runtime and apps.  It makes sense.  I installed 
org.gtk.Gtk3theme.Adwaita-dark into flatpak and Geary picked it up.  
What does not makes sense is, how it simply had worked before as I 
certainly did not have a any theme installed into flatpak and it used 
the Adwaita-dark from my desktop, so that must have changed with the 
recent upgrade.  Anyhow, thank you, I learned something.
