Unexpected hover result on nested record members

[zth]

This is using 1.0.2 on macOS.

In summary - hovering nested record members seems to show the wrong information (some form of off-by-one error). Here's a reproduction case with comments on what's happening: https://github.com/zth/rescript-editor-tooling-playground/blob/master/src/HoverIssues.res

I posted about this on the RLS repo as well way back, so it's probably originally an issue in RLS: jaredly/reason-language-server#419
