Bug 1636716 - remove incorrect borders in vertical layout on Linux. r=Paenglab DONTBUILD See before/after: {F2183389} {F2183227} The problems only appears with light theme on Thunderbird stable, but all themes in Thunderbird tip. The problem doesn’t appear on Windows, I don’t know about macOS, so I only changed the CSS for Linux, and I checked that it didn’t break borders in other layouts.
