Teleport duration on an Item display maximum distance ?

I'm trying to make a smooth camera animation for a game i'm making, i'm using the new teleport_duration tag on item display that got addend in 1.20.2. I was kinda sad when I saw you could only set a duration of 59 ticks maximum, but now i'm faced with another limitation of this feature : when I try to tp the item display a bit far (only like +100 blocks, not 1 trillion or anything) it just tp me instantly. I tried on a solo world and same things, chunks are loaded everything works when I run the function even slightly closer to the destination, the maximum distance is consistent. Is it a known problem ? Is there a way around that problem ? I failed to find anything talking about this issue online
