Online simulator is not correctly working

,

The online simulators deployed at https://sim.lvgl.io/ are not working correctly.

The javascript console gives this error:

app.fb1dbf7e7fce9b719af6.js:2 Uncaught TypeError: $(...).tooltip is not a function
    at app.fb1dbf7e7fce9b719af6.js:2:3086149
    at dispatch (jquery-1.12.4.js:5226:27)
    at elemData.handle (jquery-1.12.4.js:4878:28)

seems some jquery tooltip code is missing.

I just noticed this now myself…
is it gonna be rectified ??

Who maintains the online simulator ???
Is there any attempt to correct this ???
