Potential regression induced by PR #57302

[rhshadrach]

PR #57302 may have induced a performance regression. If it was a necessary behavior change, this may have been expected and everything is okay.

Please check the links below. If any ASVs are parameterized, the combinations of parameters that a regression has been detected for appear as subbullets.

• reshape.ReshapeExtensionDtype.time_stack
  • dtype='Period[s]'
  • dtype='datetime64[ns, US/Pacific]'
• reshape.ReshapeMaskedArrayDtype.time_stack
  • dtype='Float64'
  • dtype='Int64'
• reshape.SimpleReshape.time_stack

Subsequent benchmarks may have skipped some commits. The link below lists the commits that are between the two benchmark runs where the regression was identified.
