I know there are some workarounds in place for the "file outside current workspace" errors, but @matklad do you think that the incremental synchronization could have regressed this?
Looks like errors in
on_notification are critical, they tear down the run-loop
But still, if I'm reading the report right, they're editing
src/foo.rs.in and a build script produces a
.rs from it. So RA is only seeing LSP changes for
src/foo.rs.in (or not even those?).
