Have an issue with JA-Simpli template 2.0.0 after updating Joomla from 3.10.2 to 4.2.6.
The problem is interaction with a plugin JEvents 3.6.47 which has a calendar (month) view of events and when you hover over an event in this view you should see a tooltip appear giving a summary of the event.
This works fine in Joomla3 using JA-simpli, but the tooltip does not appear after migration to J4.
If I switch the template in use on J4 from ja-simpli to Cassiopeia then the tooltips are displayed as expected.
Remove "testing." from the URL provided to see the same page working in J3 using ja-simpli
