2019.3 breaks lerna mono-repo code highlighting and linting

I have a lerna mono repo, I open the root directory with webstorm. Each child repo lives in "./packages/<repo>". Each child repo has it's own ESLint configuration file ".eslintrc",  In 2019.2.3 code highlighting and linting was working well. Since upgrading to 2019.3 code highlighting and linting never updates. I've tried:

doing a `lerna clean && lerna bootstrap` followed by webstorm invalidate caches and restart. I've even deleted the `.idea` project dir and rebuilt. Nothing seems to force the code highlighting to rebuild.

If I open a child repo directly, code highlighting works fine.
