Peek transparency doesn't work well about vsc-material-theme HOT 1 OPEN

For what I see this is caused because I use sticky scroll in the peek. Ideally, it would be nice to fix the --vscode-peekViewEditorStickyScroll-background value so it wouldn't be transparent.

For now, my workaround is to set the previewEditor.background color to a color that works well with the selected theme. That will affect both the sticky header and the background. Not ideal, but it works:

 "workbench.colorCustomizations": {
    "[Material Theme Darker]": {
      "peekViewEditor.background": "#282727"
    }
  }

from vsc-material-theme.
