Previous Behavior
The
createV9Theme
function did not fully support some tokens in the dark theme. Specifically, there was no mapping for status tokens between V8 and V9. As a result, even in the dark theme, the token values were derived fromwebLightTheme
, leading to incorrect colors in the dark theme.New Behavior
The
createV9Theme
function now correctly detects if the provided V8 theme is a dark theme and useswebDarkTheme
as the base theme instead ofwebLightTheme
. This ensures that the tokens are correctly mapped and rendered for the dark theme.🚨 With the fix,
createV9Theme
now depends on bothwebLightTheme
andwebDarkTheme
and adds both to a bundle. We need to decide whether that is worth it.Related Issue(s)
