Now take a look at the diff in this file:

====================

The comment wasn't about only "three". You shouldn't delete
"two" and "one", obviously. By the same reason. They are
"used" in these not working tests.

t2_space_id is used in the commented code. But it looks already
corrupted, I can't even closely understand what is happening here.

t2_space_id and t1_space_id are obvious names anyway, so we probably could
just delete their declaration and assignment but keep t2_space_id usage
in the commented code.

Or comment them out too.
