Is TabRevive: Keep Tabs Active & Tab Keep Alive safe?

TabRevive lets any web page switch on its keep-alive page patches through a replayable postMessage bridge.

The extension injects a main-world script on all pages and listens for window messages with a hardcoded source string. Any page script can send that message to enable patches that keep the tab appearing active, including spoofing visibility and focus APIs, suppressing page lifecycle events, and starting keep-alive behavior such as silent audio and wake locks.
