Webstorm incorrectly reporting many hundreds of errors in a TypeScript file
Pretty often I find WebStorm gets in this state where it reports hundreds of errors in a file. But the file doesn't actually have any errors. I confirm that by running `tsc --noemit` in a terminal against this codebase and tsc reports zero errors.
It seems like WebStorm confuses itself or gets into a bad state? How can I tell WebStorm to "rerun" this file and make all the errors go away?
