Describe the bug

Project Zone / Cloud Service Provider” stencil in the GCP2 / Zones palette is rendered as an ellipse instead of a rounded rectangle.

The shape is rendered as an ellipse, with style including: shape=ellipse; perimeter=ellipsePerimeter; ...

Analysis

In Sidebar.prototype.addGCP2ZonesPalette:

var s = 'sketch=0;...;whiteSpace=wrap;';

Later in the same function:

this.addEntry(dt + 'markers', function()
{
    s = 'shape=ellipse;perimeter=ellipsePerimeter;...';

Because s is defined in the parent function scope and captured by closures, this reassignment mutates the shared style used by other entries (including “Project Zone / Cloud Service Provider”).

The bug may appear inconsistently depending on palette initialization order.

Steps to reproduce the behavior:
