This reason is that the coordinate is different from outer frame and inner frame. So we need multiply by zoom value to this min-width.

Tested on 63.0a1 (2018-07-12) (64-bit) on Windows 10. It worked fine for me. Even at the highest possible zoom level and the smallest possible window size, the close icon is always visible.
Do you mind checking again?
