SLDS classes on (new) base Lightning web components don't work

SLDS classes on base Lightning web components do not appear to work... unless I'm missing something?



When I view the component below, the margin is properly applied to the div, but not to the card.



Am I missing something?



Thanks very much!



UPDATE: Trying slds-m-around_large seems to add an arbitrary (and entirely incorrect) amount of margin. It also doesn't even add on the sides, only top & bottom.. not that I want on the sides in this case.



UPDATE 2: I witness the same (incorrect?) thing in the Web Components Playground. But that can't be the expected behavior, can it?



<template>
<div class="slds-m-bottom_large">
div
</div>

<lightning-card class="slds-m-bottom_large">
card 1
</lightning-card>

<lightning-card>
card 2
</lightning-card>
</template>

By default, custom elements are set to display: inline. By introspecting the DOM in the playground, you can also see that the lightning-card doesn't override the display property from inside using the :host selector. The margin and padding are not being applied because the lightning-card element is display: inline.



In order to get the margin and padding working as you expect you will need to set the lightning-card display CSS property to block. playground



lightning-card 
display: block;
