Neither restarting Safari nor rebooting the MacBook seem to resolve the issue. This happens several times a day and I have left it running in a high CPU usage state for more than 20 minutes before resorting to the force quit. Once Safari Networking ramps up, it stays at these levels until I force quit the process, after which it automatically restarts and settles down to more normal CPU usage - until the next time. I first notice it when my 2019 16" MacBook Pro fans unexpectedly ramp up from ~1,800 to >3,500 rpm, system power consumption jumps from ~25w to 50-60w (iStat Menus data) and Activity Monitor shows "Safari Networking" at 100%+ CPU (single core?) usage.

I haven't been able to reliably replicate the loop/hang but it seems to be related to opening or closing at least some Safari web tabs or pages.
