Describe the issue:

Many Positron panels are drawn on top of their focus outlines. When focused, only a partial outline appears. This looks sloppy, since part of the focus outline draws, but not the whole thing. It may also be an accessibility issue. Examples:

Plots pane

Missing most of the left and right focus outline; overlapped by the image.

Console tab list

Missing the top:

Variables

Missing most of the left, right, and top; kind of a weird long U thing is drawn at the bottom

Expected or desired behavior:

A focus outline should be a complete rectangle.

For example, VS Code's Problems pane unfocused:

And focused:

Reproduce the focus states in the Plots pane, Console tab list, and Variables panel, then trace the panel focus styling and stacking behavior. Done means each focused panel shows a complete rectangular outline without being overlapped or clipped.
