Animation are played faster on higher fps display

I have built and run the qt quick "Examples - Animation" on a Samsung Galaxy S21+.

The refresh rate of this smartphone is 120Hz (by default) instead of 60Hz for most other devices.

We observe that on this high fps phone, the qt animations are played twice faster than they should. in the code, animation duration are set in ms (for example 1000ms  = 1s for the easing curves example) and should be independent of the refresh rate of the device where the application is built.

Comparison side by side with an other classical 60Hz smartphone (app built from the same code) clearly shows that animations are twice faster on the 120 fps.
