Is there a minimum line-height (per font-family)? Reducing line space gap

[pstein]

1. Lets start with an example web page (from german computer magazin):
   
   https://www.heise.de/newsticker/meldung/VMware-Workstation-14-braucht-juengere-Prozessoren-3847372.html?view=print
   
   When you look at the bottom of this webpage you find a list of link lines.
   
   I want to shrink the space gap between each of them. Therefore I applied (afterwards through Greasemonkey) the following CSS statement:
   
   pre, code { font-size: 10px !important; line-height: 9px !important; }
   
   Reduction of line-height works until 10px (even when the font-size itself is biggger !!!).
   
   Specifying a lower value for line-height than 10 does not work any more.
   
   Why?
   
   How else can I reduce the space gap between the link lines?

They are within a paragraph that has its own set line height by default, that the child element are within, that is what needs adjusting.
