screen recording of the issue

SUMMARY

I've run into this with both rust-analyzer and pyright, it's not language server dependent.

The following trivial snippet reproduces the issue for me with pyright (which I'm using via a `pyright-langserve --stdio` LSP plugin setting):

import sys

def main():
    sys.exit(0)


See video for effect if you can't reproduce.

STEPS TO REPRODUCE
1. Use the pyright language server and open a file containing the snippet above.
2. Hover over the `exit` token, wait for the box to appear, and move the cursor around on top of `exit` for a while.

OBSERVED RESULT

See summary.

Pyright version 1.1.376
