Bug#945240: evolution: HTML messages become unreadable after changing theme

Package: evolution
Version: 3.30.5-1.1
Severity: important

I recently changed GNOME's theme from Adwaita to Adwaita-dark.  This
changed Evolution's default text colour for HTML display from black to
white, but the background colour remains white.  (The default colours
in the composer appear to be unchanged.)

If a received HTML message sets background and text colours, it
displays properly, but if it does not (which seems to be the default
behaviour of Thunderbird) then it is unreadable in Evolution.  (A
temporary workaround is to select all text.)

The same problem affects HighContrast and HighContrastInverse
themes, so this is an accessibility issue.
