Subject: My Calendar 3.8.7: duplicate heading IDs fixed, but aria-labelledby now points to the old ID

Hello,

Thank you for the 3.8.7 fix for duplicate heading IDs on multi-day events. I updated today and the duplicates are gone. Each day of a multi-day event now has its own heading ID.

One thing was left behind. The event details container still uses the old ID pattern in aria-labelledby, so the reference no longer matches any element.

Example from our calendar (list view, details open in a modal), event occurrence 1429, a multi-day event:

Heading:


Details container:


No element with id="mc_1429-title-harc-calendar" exists on the page. The same thing happens for single-day events. On our October view, 30 of 35 aria-labelledby references point to an ID that is not there.

It looks like the heading ID changed in my-calendar-output.php (id='title-$container_id-$id'), while the mc_{occur_id}-title-{calendar_id} pattern is still used elsewhere, for example the aria-describedby values in my-calendar-templates.php (around lines 924 and 2520).

Setup: My Calendar 3.8.7 (free), calendar ID "harc-calendar", list format, details in modal. Page: https://harcmt.org/calendar/

The effect is small. Everything works for sighted visitors, but screen readers lose the event title as the label for the details panel, and accessibility checkers report a broken ARIA reference.

Thanks for the quick work on the first fix.
