Git commit e3f43758f6997dee33e0d4fb7c7afcda44312a35 by Christoph Wolk. Committed on 07/03/2025 at 22:25. Pushed by cwo into branch 'master'. applets/systemtray: remove KSortFilterProxyModel binding loop The systemtray's KSortFilterProxyModels bind to the model exposed on the C++ side, which are in turn QSortFilterProxyModels. This causes a binding loop. The binding is unnecessary in first place though, the (sorted) models are marked as CONSTANT and cannot themselves change (their contents can, of course, but it's still the same sorted models). So we can just set it once on startup and avoid the bindings and any errors or effort associated with them.
