Bug

Body

what happened

• open some file on GitHub
  • e.g. https://github.com/renovatebot/renovate/blob/b23700d749e0f483ed7afc1afcca9a328902a9ef/lib/config-validator.ts
• click anywhere on the code lines (the textarea which has an id id="read-only-cursor-text-area" )
  • 
• press . (period) key
• page will be navigated to https://github.dev/github/dev
  • no files are opened
  • 

expected

• page should be navigated to https://github.dev/renovatebot/renovate/blob/b23700d749e0f483ed7afc1afcca9a328902a9ef/lib/config-validator.ts
  • the file (e.g. lib/config-validator.ts) is opened and the repository (e.g. renovate/renovate) is set as workspace
  • 

This is the same behavior with pressing . key without clicking (focusing) code.

Well, it is fixed before I knew it.
