References and Relevant Issues

Detailed Description of the Pull Request / Additional comments

Not really relevant, but how I found out this was missing: It was experimental.moveCursorWithMouse early in the feature implementation PR. I was in my personal list to check out the feature, finally I tried to test it today, couldn't make it work cause I was trying with moveCursorWithMouse. VScode also wasn't much help as experimental. autocomplete didn't contain this value. After looking over the PR thoroughly and the relevant docs PR I realized my mistake.

Validation Steps Performed

I set $schema to my patched one's url and vscode no longer complains about experimental.repositionCursorWithMouse. Autocompletes and also shows description on hover.
