I can confirm. My workaround which predates the stylealternative mechanism also stopped working, so there must be an issue on the level of font feature selection.
\definefontfeature [math-text] [math-text] [ss04=yes] \definefontfeature [math-script] [math-script] [ss04=yes] \definefontfeature [math-scriptscript] [math-scriptscript] [ss04=yes] \setupbodyfont[lucidaot] \starttext \startTEXpage[offset=3bp] $\mathcal A$ \stopTEXpage \stoptext
