The dismiss button in the WC admin notices `legacy_shipping` and `no_shipping_methods` was not fully clickable due to a custom CSS applied to them. This custom CSS was used to add a background image to those notices. More specifically, the problem was caused by the use of `position: relative` applied to `<p>` elements. I couldn't find an easy way to fix this problem keeping the custom background image, so I opted to remove it to make the design of all notices identical (besides the background image, the custom CSS also added a few other differences to those to notices like the font size of the notice title).
