Can repro. @aiday-mar can you look into this in debt week?

Hi thank you for filing this issue. After some investigation I believe sticky scroll works as intended, it is reflecting the editor lines which themselves have a growing number of inlay hints appended to them. You can see this happen in the following screen recording where we briefly see the actual editor lines with all the extra inlay hints.

This behavior is also mirrored in the following issue https://github.com/microsoft/monaco-editor/issues/4700. I will close this issue, as it is a consequence of the root cause of the issue.
