The real-time visitors live widget seems not to be fully recovered since Matomo 3.10.0 (possible with fix #14374).

After live_widget_refresh_after_seconds period "timed out" without any new visits/actions, the widget doesn't refresh anymore.

Only after a browser tab change or page refresh new visitors/actions during the live_widget_refresh_after_seconds period refreshing correctly in the real-time live widget, until the live_widget_refresh_after_seconds “timed out” again.

The live_widget_refresh_after_seconds period "timed out" without new visitors/actions.

I can reproduce this behavior since Matomo 3.10.0 with a clean installation, in my case on macOS with Safari and Chrome.

New visitors/actions on website during the default 5s interval (after viewing Matomo dashboard) are viewing/refreshing correctly. After no visitors/actions, e.g. for 20s, the widget doesn't refresh anymore (until a browser tab change or page refresh).
