Can you make this like browser
https://cs.chromium.org/chromium/src/chrome/browser/BUILD.gn?rcl=0&l=59 so the
type is always split_static_library?

Done.

If (per the bug) LTCG is mostly what makes this happen, then maybe use 

  if (is_win && is_official_build) {

to also match the browser.lib one.
