UI elements being forced to dark mode

Hi, I updated to Firefox 146.0 this past week and immediately noticed that the UI elements (scrollbars, sidebar, tooltips, etc) are once again in dark mode; the main websites window and the firefox settings remain in light mode (as set by my user preferences). I've been using browser.theme.toolbar-theme and browser.theme.content-theme to force light mode of all UI elements regardless of theme and as of this last update they have stopped working (editing them to any value of 0,1,2 does not make a noticeably change to the UI). What internal setting changed to stop firefox from using the browser.theme.(etc) settings and what can I edit to get them back? Thanks, Bre
