auto outline corner offset
Reproducer
Live rendering
The green box combines four non-round corner shapes with
outline: auto and a 5px outline-offset. In affected
Chromium builds, the focus-ring path is expanded a second time.
Red pixels mark the geometry changed by removing the duplicate outset.
Expected behavior
The outline path should use the rectangle already expanded by
outline-offset and the already-adjusted corner radii. It should
not apply the same outset again while constructing the contoured path.
Minimal CSS
.shape {
width: 200px;
height: 200px;
border-radius: 140px;
corner-shape: bevel notch squircle scoop;
outline: 15px auto purple;
outline-offset: 5px;
}
