--- Comment #1 from Noam Rosenthal <noam at webkit.org> ---
I double-checked the spec, and indeed it should be stable throughout the lifetime of the document.
In https://w3c.github.io/hr-time/#dfn-estimated-monotonic-time-of-the-unix-epoch, the "estimated monotonic time of the Unix epoch" is initialized once, while in https://github.com/WebKit/WebKit/blob/main/Source/WebCore/page/Performance.cpp#L86 it's effectively computed every time timeOrigin() is called.
