Description
This only seems to apply for structs which contain an array of structs. Linear View does not traverse the array to make the selected region only contain the selected line(s).
Selecting any element in the array in the example yields a selection region of all 8 items in the array. Expected behavior would be for the selection to only contain the one selected item.
Example: test.bndb.zip

Research direction
Start by opening the provided test.bndb.zip in Binary Ninja and reproducing the selection behavior in Linear View. Trace how selection regions are computed for arrays of structs, then verify that selecting an element includes only the selected line rather than all eight array items.
