Thank you for filing this issue! I can confirm this is reproducible on Windows using Firefox Nightly and on Mac when showing scollbars is set to "Always". The issue is related to RDM overriding scrollbar styles with its own stylesheet: https://searchfox.org/mozilla-central/source/devtools/client/themes/floating-scrollbars-responsive-design.css .
