Description

[Shane Hughes [:aminomancer]]

STR

1. Add a new integer pref ui.useAccessibilityTheme and set to 1
2. Open the browser console (accel+alt+shift+i)
3. Enter Cc["@mozilla.org/browser/browserglue;1"].getService().wrappedJSObject._showUpgradeDialog(); and hit enter.

Expected

Browser content should still be visible underneath the dialog, with a 50% opaque dark gray overlay.

Actual

Browser content is totally obscured by a 100% opaque white background.

I‘ve verified this issue using the latest Firefox Nightly 106.0a1 de build (Build ID: 20220918214503) on Windows 10 x64, macOS 12.5.1, and Linux Mint 20.2 x64.

• The Onboarding spotlight overlay is transparent in HCM, and the new tabs elements are visible.
