Subject: bug#60087: 29.0.60; c++-ts-mode conflict with electric-pair-mode
Date: Thu, 29 Dec 2022 14:10:13 +0800

Hi all,

I can confirmed that the latest commit (909091d7578b7225601b202fb9257dedae879e9a)
 of Emacs-29 have been fix this bug#60087,  and `show-paren-mode` also get the expected result
 when c++-ts-mode enabled.

I think we can close this bug now.
