Describe the issue you are experiencing

The analog display runs too fast. The longer the page is not completely refreshed, the greater the advance. Both the digital and analog clocks use the same sensor. It seems to get worse when the page is running in the background. Browser: Chrome 145.0.7632.46 (Official Build) (64-bit)
Same behavior in Firefox 147.0.3 (64-bit)

Normal operation:

Safe mode:
