larger point when zooming in in interactive mode

You can use the parameter size_unit='x' (or size_unit='y') in geom_point.

while this solves the issue, it introduces a new issue.

size=1 makes the size 1 unit of x when size_unit='x'

So, if your data span from 0 to 10 vs 0 to 1000
your points will be 100 times smaller in the seconda scenario.

letsplot handled the issue. It is up to implementing in cellestial.
