Linting vanishes on warnings with no errors on reload with no change.

To reproduce, load code that has warnings and no errors. Warning lint will work. Reload the code with no changes; warning lints will vanish.

It appears that the cause is the warning code does not disappear from the interactive window so presumably the starting point of the search is not reset.

Reproduce the issue by loading code with warnings and no errors, then reloading it unchanged; inspect the warning lint handling around the interactive window and its search starting point. Done means warning lints remain visible after the unchanged reload, without affecting the reported errors.
