Even though this works locally, it fails on the bots. Have not figured out why
the bots can't find this file (hitting
https://cs.chromium.org/chromium/src/chrome/test/base/javascript_browser_test...).
Any help is appreciated.

trying doing something like:

suiteSetup(function() {
  return this.importHtml('.../search_settings.html');
});

in search_settings.js (as your browsePreload doesn't depend on
search_settings.js directly)

Added chrome/browser/resources/settings to the appropriate list in
chrome/test/BUILD.gn which makes all settings src files available to bots
(similar to ui/webui/resources/js). Let me know if you are OK with this fix,
instead of adding a new dummy search_settings.html file.
