My app includes the websocket, that should work continuously. However, if tab isn't active for more than 5 minutes, the ping message from my client don't send anymore, and connection closes as result.

I've read advices such as changing some settings in chrome://flags (e.g. 'Tab Freeze' or 'Calculate window occlusion'), but as for 'Tab freeze' - it looks like it's already released feature that set by default, and now it's not listed at chrome://flags anymore. And as for 'Calculate window occlusion' - it works only for Windows. Another advice that i find was related to chrome://discards, but this link doesn't open on Chrome for Android.

Is there any way to prevent chrome of freezing tabs and make tab's work stable?
