Black boxes behind DuckDuckGo sidebar text

[atouchet]

Page tested: https://duckduckgo.com/

Open the sidebar with the hamburger button and the text that appears is surrounded by black boxes.

Example image (Servo on the left, Firefox on the right):

Tested in Windows 10.

Nothing happens in a local macOS build when I click the hamburger menu button.

I can confirm the latest master still has this issue (of not opening the sidebar), even on macOS 10.12.6 (16G29) and not on FirefoxNightly 57.0a1 (2017-08-04) (I'm not sure if it's running servo already).

This is the result for ./mach run https://duckduckgo.com/:

Is there a way to get a debugger to see what happens when I click? -p doesn't show anything useful. Sorry if this is answered elsewhere, haven't found it.

[jdm]

There is no such debugger, unfortunately.

This is fixed for me now, although it appears the theme selection icons are now busted.
