Comment (by siliconforks):

 The reason this bug is occurring is that the `.primary-navigation >
 .primary-menu-container` (desktop menu) is visible when `(min-width:
 482px)`, while the `.menu-button-container` (mobile menu) is visible when
 `(max-width: 481px)`.  That means that, if 481px < width < 482px (e.g.,
 suppose the width is 481.5px), then neither menu will be visible.

 I'm not sure how the original reporter was able to reproduce this at
 481px; I suspect when the browser was displaying "481" the width was
 actually 481.5 (or possibly some other fractional value between 481 and
 482) and rounded down or truncated for display purposes.
