and the following is the result of that `printToLog` for material 2 and 3 ``` Material 2 working 09 25 20 35 08 518 6279 6298 D TAG Node 4 at l=0 0 t=136 0 r=1440 0 b=360 0 px 09 25 20 35 08 518 6279 6298 D TAG Text = Name 1 Home world 1 09 25 20 35 08 518 6279 6298 D TAG Actions = GetTextLayoutResult Material 3 not working 09 25 20 28 03 039 5953 5972 D TAG Node 4 at l=0 0 t=136 0 r=1440 0 b=388 0 px 09 25 20 28 03 039 5953 5972 D TAG IsTraversalGroup = true 09 25 20 28 03 039 5953 5972 D TAG | Node 5 at l=56 0 t=164 0 r=1384 0 b=360 0 px 09 25 20 28 03 039 5953 5972 D TAG Text = Name 1 Home world 1 09 25 20 28 03 039 5953 5972 D TAG Actions = GetTextLayoutResult ```

So in case this is useful to others the key reason test is failing is that in Compose Material 3 `ListItem` is using a `Surface` whereas it didn t in Material 2 where test was passing and `Surface` in turn contains following Not fully sure what best fix is yet ``` semantics mergeDescendants = false isContainer = true ```

using following works but seems like bit of a hack ```rowNode onChild assertTextContains person name ```
