Locals and Expressions debug view loose selected item on expansion

Steps to reproduce

Start a debug session, set a breakpoint, run a program, and hit the breakpoint. Focus on the "Locals" view, use the keyboard to navigate to the specific item, and then expand it with key press (Right arrow (→, Qt::Key_Right) on my system).

Actual behavior

Item is expanded, but TreeView forgets what element was selected. I.e. when the user presses "Down" on the keyboard, the topmost item is selected rather than the first child item of the recently expanded item.

Expected behavior

Item is expanded, TreeView keeps the current item selected. Pressing down selects the first child item of the recently expanded item.

IIRC, this also happened with older Qt Creator versions.
