Remote SSH Yarn install

I have a vagrant vm that I access through SSH from PHPStorm. To run some scripts I created a "Remote SSH External Tool". But the terminal output is garbled. A simple "yarn install" for example (with filling progress bars) doesn't seem to update the terminal correctly, but adds the new progress bar status next to the old one. Also it shows no colors.

When I run the same manually through "Start SSH Session", it does look right.

Is this a bug in the Remote SSH External Tool or am I missing a setting somewhere?
