theme_changed, miniApp.isDark doesn't work on Android and IOS

[artyom12211]

Device on IOS 18 doesn't detect this event.
Android throws error when I am manually changing theme on Telegram "Uncaught TypeError: Cannot read properties of undefined (reading 'WebView')
at :1:17. "

PS maybe I something don't understand :(

Stetps to reproduce
App.vue

import {  
miniApp  
} from '@telegram-apps/sdk-vue';  

const isDark = useSignal(miniApp.isDark)  
// OR   
on("theme_changed", (payload) => {  
 console.log('payload: ', payload)  
});
