I just navigated to ptwiki for the first time in a while (maybe the first time ever), and I found I had a notification. The bolded link led to this URL:
I'm not mentioned there. I am, however, mentioned in a section further down the page with an identical section heading:
I assume that at the moment Echo is not checking for duplicate headings when making notification URLs. If Echo could check for this somehow it may stop users from getting confused by notification links that point to the wrong section.
T2111: Return to the correct section after section edit for a heading that exists multiple times
T4831: Links in autogenerated summary in page histories may point to wrong section or to nowhere
