tcolorbox & parskip & minted

I want to use minted code extract within tcolorbox, but it fails to properly set the parskip of the first box. I already use parskip=false inside the tcolorbox, but it doesn’t solve the issue.

usepackage{wrapfig}
usepackage{geometry} 
geometry{paperwidth=7in, paperheight=9in, bindingoffset=0.35in, left=0.7in, right=0.7in, top=1in, bottom=0.8in}
usepackage{float}
setlength{parskip}{0.05 in}

usepackage{minted}
usepackage{csquotes}
usepackage{upquote}%straight quotes in minted
setminted{fontsize=small, breaklines=true, breakbefore=., breakafter={,,+,~,space,:}, showspaces, space=~, frame=single, numbers=left, numbersep=5pt, highlightcolor={red!25}, fontfamily=tt}
