cd31e113c0switched to passing options as keyword arguments, which always creates a new hash.9e4ff29f74removed a now-unnecessary call to `dup`, since the options could no longer be accidentally mutated.a55620f3faswitched back to passing options as a positional argument for Ruby < 2.7, but didn't restore the call to `dup`, which meant that the same options hash was now passed with every method call and mutations leaked from one call to another.
