[Dashboard] 'requestAnimationFrame' handler took <N>ms and memory leak

[dong-king]

Describe the bug when i run JSON.eez-project in eez-studio exmaple, the messages('requestAnimationFrame' handler took <N>ms) are continuously output in DevTools.

And there is a memory leak in this example. when running this example for a while, the memory usage keeps rising.

I feel that the message's generation is related to the defined CountryCity structure.

I didn't notice any memory leak while running this dashboard for about 30 minutes. Memory can go up for a period of time, but it will go down again after garbage collector cycle.

As for this warning message, it's a performance issue and I've made some optimizations so it should run faster now and probably won't show this warning anymore.

It is not a memory leak. The memory usage keeps increasing because DevTools has been open, and the memory it occupies continues to rise.
