Inspector doesn't always expand/collapse rows in trees with arrow keys
- Run an app with the Inspector
- Focus its window
- Keynav down into the objects tree/column view
- See that Up/Down cursor keys work as expected to change row, but Shift+Right/Left do not work as expected to expand/collapse the current row.
The latter does work iff we first press Tab or (non-Shifted) cursor right. At that point, the current list row flashes a focus outline briefly. Conversely, if we Tab back or press Left, we see a flash, and Up/Down stop working again.
It's harder to replicate with other trees, e.g. the CSS Nodes one, but it can be done, or if they initially work to expand/collapse, they can be made to stop working by pressing Left or Tabbing backwards, whereupon - again - Up/Down continue to work, but Shift+Left/Right stop.
Maybe a more general problem with ColumnView, or somehow caused by the SearchBar and its key-capturing?
