1418561 - Zoom percentage in hamburger menu has dark text on dark background when using dark GTK3 desktop theme

Status: RESOLVED DUPLICATE of bug 1379725

(Firefox :: Toolbars and Customization, defect)

Description

[[e-mail]]

Attachment: The zoom percentage label when the mouse cursor is not hovering over it (top) and when it is hovering over it (bottom, cursor not shown)

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:52.0) Gecko/20100101 Firefox/52.0
Build ID: 20100101

Steps to reproduce:

Similar to bug 1418231, using a dark GTK3 desktop theme such as Adwaita Dark causes the zoom percentage label in the hamburger menu to appear with an illegible colour scheme.


Actual results:

The text and background of the zoom percentage label are both white. Hovering the mouse over the label darkens the background somewhat, making the text legible.


Expected results:

The label should have either dark text on a light background, or light text on a dark background.

Looks like the background color comes from https://hg.mozilla.org/mozilla-central/rev/cb9964c00980#l5.153
Moving component to find out from where the foreground color comes.
Guessing this is a regression from that changeset.  (From the switch to photon, really.)
