Javascript documentation shows MDN website instead of short description - how to remove/toggle?

Hi,

When I press CTRL+Q on a function, I get the whole MDN site returned:

And in the very bottom there is the "normal" documentation (below "By Mozilla Contributors....):

How do I remove the MDN part? I have tried:

1) Remove PHPStorm 2020.3

2) Delete all files in appdata

3) Download and install PHPStorm 2020.3

3) Test on a new blank project, as shown above

I am using default Phpstorm- and project settings.
