App theme is not reflected in the in-app browser on Edge for Android

In the MS Edge for Android, we can set the app theme appearance within the app separately from the system dark mode setting, but the in-app browser (Chrome custom tabs) such as Twitter will reflect the system settings instead of the in-app settings.

The image was taken using the Twitter app's in-app browser with the system in dark mode and Edge in light mode, but the Edge menu is in dark mode.
