This is more looking like a DataContext propagation. In general, though, this particular behavior is generally not used, as DataBinding is on individual items is used. This is what likely made this issue go under the radar.

It seems to be specific to ListViewBase, as the following playground repro shows: https://playground.platform.uno/#1626a15d
