Sorry for the late reply. It appears that some of the code that this PR is trying to change has already been updated in trunk, causing a conflict. Can you resolve this conflict?

Once this PR is merged, all isSmall prop replacements should be complete.

Thank you!

Sorry! I think I did something wrong with the operation!
