Opening files via Storefront Toolkit links doesn't work consistently and shows warning messages

[BerndRoeder]

Describe the bug
When clicking the Controller, Template or Pipeline links in Storefront Toolkit, I expect that the respective files are opened in VS Code. However, this doesn't work consistently. In some cases I have to click the links multiple times before the file is opened.
For each click on a link, VS Code also shows a warning saying "Unable to find ..." with the path of the file I've just clicked, even though the file exists. These warning messages even appear in the cases where the file was successfully opened.

To Reproduce
Steps to reproduce the behavior:

1. Go to Storefront Toolkit
2. Enable the "Cache Information" feature
3. Hover over any of the cache info icons on the page
4. Click one of the Controller, Template or Pipeline links

Expected behavior
The respective file is opened in VS Code and no warnings are displayed.
