Setting "browser.display.use_focus_colors" value to "true" causes odd overlay with specific image viewer on many webpages.

Reproducible: Always

Steps to Reproduce:
1.Type about:config on Location bar and enter.
2.Search for and change browser.display.use_focus_colors to true
Actual Results:  
Go to https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/ for example.Scroll down to Image Gallery.Open the first image and click Next to see the next image.A green overlay blocking half the picture is shown on the right side of the image viewer.Now click Prev to see the previous image.The overlay now blocks the left side of the image.

However this affects not only addons.mozilla.org but every single webpage where this type of image viewer is used.

Expected Results:  
Setting this value should allow the use of custom focus colors without affecting image viewer on webpages.

Using default theme and preferences (prefs.js)
No user.js,userContent.css or userChrome.css in profile folder.

Yes.

This preference causes anything matching ":focus" and anything matching ":focus>font" to have the default focus foreground and background color unless the page styles them otherwise.

The default focus background color (the "browser.display.focus_background_color" preference) is #117722 which is a greenish color.  So it sounds like everything is working as expected, and this bug looks invalid to me...

That said, it might be worth filing a separate bug on allowing "transparent" or other CSS values as values of "browser.display.focus_background_color" (right now only colors of the form #rrggbb are supported).
