Yandex.News widget - memory leak?

Recently noticed that the MacBook is slower than usual. Got into monitoring the system and saw that one of the widgets (the DashboardClient process) takes 800 meg RAM. By simple actions (sudo kill;)) it was found that the memory eater was Yandex.News. So if you use the same, be careful.

I like the widget by itself. I hope they fix it.
Thanks for attention.
