[BUG] "Insert After" matches line prefix, not the whole line

[pjeby]

Describe the bug "Insert After" matches a line prefix (startswith?), not the whole line

To Reproduce If a capture choice is set to insert after "## Do", it will instead insert it after `## Done" if "## Done" is before "## Do" in the file.

Expected behavior It should insert after the exact match, at least by default.
