bug#67326: 29.1.90.1; time-stamp slowdown in large org file after org-refile-get-targets, caused by e7b5912b23 (Improvements to long lines handling)

Hi Yuchen,

Thanks for your bug report, and sorry for the delay.

I can't reproduce that bug alas, because I don't have that file.  I 
understand that it may contain private information.  Could you perhaps 
create a censored version of that file, and send it to me (privately, a 12 
MB attachments is too large for this list)?

This bug is likely not directly related to that one, as Ihor confirmed 
that it was fixed (and no other similar reports were filed since then).

The reason for that is that development happened on feature branches, on 
which commits were not tagged as fixing specific bugs.
