Issue Summary

With a black/dark body background color set in page customizations, along with white/light text, the component selection dropdown on the uptime history page and subscribe button have very difficult-to-read text

Steps to Reproduce

1. As a page admin, navigate to Your page -> Customize page and emails -> Colors
2. Set background color to something dark (e.g. #2A2F42)
3. Set font color to white (#FFFFFF)
4. Save color customizations
5. Visit the page as a viewer, and click the Subscribe button (or go to History -> Uptime, and click through the component selector)

Expected Results

Dark background color comes in to the Subscribe and Component selectors

Actual Results

Subscribe and Component selectors retain the white background, so there is unreadable white text on white backgrounds

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
