Please make the default stroke position outside:

Most of the time designers use strokes to create borders:

Most shapes in Figma got an inside stroke on the layer’s path and if there are lines the stroke is centered.

The default behaviour of web dev and mobile dev (CSS and other libraries) is, default borders are outside.

But in CSS the default behaviour of the border is

box-sizing: content-box

box-size: border-box
