I suspect that //chrome/browser/downloads will need to be pulled into its own target, or that safe_browsing will need to be refactored.

Build error that closed the tree: https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/win32-rel/9928

Compilation errors below. The theme seems to be that safe_browsing files include //chrome/browser/ui/browser.h directly, via //chrome/browser/download/download_commands.h, or via other files in //chrome/browser/ui.
