The navigation to component TS files by cmd/ctrl-clicking on the component or methods or variables in the template file just stopped working. Like in, yesterday it worked and today it doesn't. Without any changes to settings or similar things. My colleague also using Webstorm also report erratic behaviour for component navigation. My colleague using IntelliJ doesn't report this issue.
A similar post has including node_modules as a solution, but this doesn't work for me and it has never been an issue before.
I've tried updating to the latest Webstorm version to no avail (see build info below).
The components are currenlty highlighted as unknown html element.
