with dark desktop theme: unreadable guard text: coloured white with bright grey background
I'm using the GNOME desktop on Debian GNU/Linux and have enabled the dark theme. When I click on the site (i) info icon, the text "Your Guard node may not change. Learn more" is in white (except for blue on "Guard" and "Learn more") and the background is bright grey. Consequently the text is unreadable except for the blue parts.
I suggest that since the background is always bright grey, the text should always be in black. Alternatively, the background could be reverted to the default background colour.
I'm using Tor Browser 8.0.4 (Firefox 60.4.0esr and Torbutton 2.0.9).
