Yarn commands are being run in the Terminal view instead of Terminal+.
Steps to replicate :
1. Set the yarn.runInTerminal to true in the CodeMix > User Settings preferences page.
2. Select any angular project in the explorer view, and select ‘Yarn Start’ from the Command palatte (Ctrl+Shift+P)
3. Note that the output is opened in the Terminal view and not the Terminal+ view.
