I’ve submitted PR #1251 now; it appears to solve the saving issue on my local installation. Getting the code to instead select the heading would be a better solution, but that would also suffer the same issue, if that heading should be longer than 124 bytes, so limiting the title length is probably required any way.

Closing as the PR has been merged.
