Hi, unfortunately it's still reproducible on the latest Nightly Build #20560606 from 02/25 using the following devices:
• OnePlus A3 (Android 6.0.1)
• LG Nexus 4 (Android 5.1.1)

On the LG Nexus the "Desktop site " is always red while using the "Dark" theme.
On the OnePlus the "Delete browsing data" turns to red after changing a couple of times Fenix's theme.

Add the download confirmation dialog to this as well.

Alright, let's try again 😅
Couldn't reproduce the "Delete Browsing Data" trash icon one but I _think_ I got the others (at least on my emulator)

This is not fixed entirely yet: the "+" icon from Settings-Add-ons is red, both in light theme, and dark theme.
The rest of the buttons/items are displayed correctly.
Verified on the latest Nightly build from 2/28, and on Beta V4.0.0-beta.2, with Xiaomi Mi4i (Android 5.0.2), and Xiaomi MiPad 2 (Android 5.1).

Okay let's close this ticket now for #8641 since I think the remaining issues overlap :)
