Segment ids > 2**53 - 1 are not supported

Originally, this was a bug report, but it can be traced to the partial 64 bit support.

Context

Expected Behavior

Hovering should work.

Current Behavior

Hovering doesn't work for the linked DS.

Steps to Reproduce the bug

The dataset in question uses segment ids greater than 60 bit which is greater than Number.MAX_SAFE_INTEGER. Strictly, this is not supported right now (2**53 is the limit).

See #6581.

I'd rather consider #6581 as the parent issue and keep this open.
