I'm probably just missing something from here or the build file, but what's
limiting these tests to running on Mac?  I don't see any ifdefs or a
platform-specific section in content/test/BUILD.gn, but it does look like the
tests run on the Mac bot and not the Linux bot.

I would, maybe say the .mm extension does the job? Probably this test file is
automatically ignored on other platforms? This seems to be the case with some
other files as well, e.g., "render_view_browsertest_mac.mm".

+// the string range which includes the first word. Then it uses the returned
+// point to query the text again and verifies that correct result is returned.

+// file which is "This".
