Day is repeated multiple times when the seconds are shown on the tooltip. The letter e is also added in front of it.

SUMMARY

I'm seeing the day being repeated multiple times on the tooltip when "Show seconds: Only in the tooltip" is enabled, with the addition of "e" in front of it. This is on Neon Unstable. Check the attached screenshot.

Important: The system was originally in Brazilian Portuguese, then I changed it to American English, but the dates are still shown in Portuguese for some reason. I went to the Region and Language KCM and changed the date format to the American one, but even after a restart, it still shows the name in Portuguese. If this bug cannot be reproduced in normal conditions, this could be the reason. Try changing your date format and restarting to see if the bug can be reproduced.

This was possibly caused by https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/2232

STEPS TO REPRODUCE
1. Hover over the tooltip
2. If you cannot reproduce, try changing the date locale and restarting

OBSERVED RESULT
The day is repeated multiple times and an "e" is added. For instance, today is Feb. 25th, and here it says "25 25e Fevereiro 25e 2023".

EXPECTED RESULT
The day should be shown as normal, the same way it is shown when the seconds in the tooltip are disabled.
