Bug#907222: Preferences: Tracks>Spectrograms panel (only) does not respect GTK theme

[Reuben Thomas <rrt@sc3d.org>]

Package: audacity
Version: 2.2.1-1
Severity: normal

The Debian package seems to be patched to make Audacity work properly with
dark themes (thanks very much!).

Oddly, the Tracks>Spectrograms panel of Preferences still does not work in
this regard: the background comes up white with white text on my
Adwaita-dark–themed GNOME desktop. To be clear, all the other Preferences
panels come up as desired, with dark coloring.
