Intellisense unable to find another component in the same directory

Webstorm's Intellisense has never been much more use than nothing at all.  It cannot even suggest basic React lifecycle methods such as render() and componentDidUpdate() inside a React class.

I have given up filing bug reports.  The system is designed to deflect criticism rather than use it constructively, and the feeling I get is that the staff feel that they are doing their customers a big favour by taking the reports seriously.  If I mention a bug, instead of a member of staff taking the trouble to test it, I am expected to spend my own time recreating the exact point when the error occurred and then help them with videos, screenshots, etc.  Even then, nothing is ever done.  There are hundreds of grammatical mistakes in the help text: my suggestion was to get a native speaker to check the text (which would have cost a couple of hundred dollars).  Instead, the mistakes will stay there unless I write a separate report on every single one.  In some places the text is incomprehensible; in others, it is wrong.  Nobody has ever thanked me for dozens and dozens and dozens of bug reports, the vast majority of which have never been fixed.

Before I give up entirely and go over to VS Code, is there any hope that some of the more obvious problems can be fixed? Frankly, though, until the bug report system is fixed, this won't be possible.
