Summary	0006212: Participants' labels are covered with an X Icon after upgrade to 5.12.8
Description	Dear SoGo-Team, after upgrading to SOGo v5.12.8 (not to be tested as it was highly recommended due to major undisclosed vulnerabilities (https://www.sogo.nu/news/2026/sogo-v5128-released.html) there appearing X icons over all participants' labels which make the participants' status (e.g. accepted or declined or no answer) unreadable. This appears both in mail invitation as well in calendar entry and shall be fixed soon. The error did not occur on v5.12.5. Also it is possible to click on the X icon and then the invited participant will disappear. It is not clear, if there are messages sent or so on. The Bahnkonzept team from Dresden/Germany P.S. The version 5.12.8 does not appear in the SOGo bugtracker changelog (https://bugs.sogo.nu/changelog_page.php) and cannot tagged in the reports here. Therefore we used 5.12.6 instead.
Steps To Reproduce	Simple have a look in all calendar entries. No special steps needed.

qhivert 2026-05-20 14:25 administrator ~0018477	Hello (I've added 5.12.8 tag) It seems to be already fixed with the current nightly. Could you check it? We're reviewing the differents regression from 5.12.8 and we will make a 5.12.9 soon enough.

bahnkonzept 2026-05-20 20:10 reporter ~0018481	Dear Quentin, unfortunately our admin in on vacation this week, so we can check only next Tuesday as we're using Mailcow docker from https://mailcow.email/ and I cannot implement the nightly build on my own. We will test next week and let you know ASAP. The Bahnkonzept team from Dresden/Germany
