Description

When using bullet lists inside named slots of an MDC component, the rendering behavior is inconsistent.

The same markdown syntax (- item) renders as a proper <ul> in some slots, but (no <ul>) in others:
I tried to figure out before posting this if it was something i was doing wrong or if its a real bug.
See: nuxt/nuxt#35149

Rigth now the only viable workaround is wrapping it in divs.

code example:

BulletTest.vue

<template>
  <div>
    <div>
      <strong>slot-a: Renders UL</strong>
      <slot name="slot-a" />
    </div>
    <div>
      <strong>slot-b: does not render UL anymore</strong>
      <slot name="slot-b" />
    </div>
    <div>
      <strong>slot-c: if i indent it renders UL again</strong>
      <slot name="slot-c" />
    </div>
    <div>
      <strong>slot-d: but if i do it consistently again it doesnt render UL</strong>
      <slot name="slot-d" />
    </div>
    <div>
      <strong>slot-e: if i wrap it in div it works</strong>
      <slot name="slot-e" />
    </div>
    <div>
      <strong>slot-f: and for some reason the 2nd one also works</strong>
      <slot name="slot-f" />
    </div>
    <div>
      <strong>slot-g: but this one breaks again</strong>
      <slot name="slot-g" />
    </div>
    <div>
      <strong>slot-h: the only way to keep it consistent is to wrap all bullets in a div</strong>
      <slot name="slot-h" />
    </div>
    <div>
      <strong>slot-i:</strong>
      <slot name="slot-i" />
    </div>
    <div>
      <strong>slot-j:</strong>
      <slot name="slot-j" />
    </div>
    <div>
      <strong>slot-k: mg1986jp suggestion test with enter before and after</strong>
      <slot name="slot-k" />
    </div>
    <div>
      <strong>slot-l: mg1986jp suggestion test with enter before and after</strong>
      <slot name="slot-l" />
    </div>
    <div>
      <strong>slot-m: mg1986jp suggestion test with enter before and after</strong>
      <slot name="slot-m" />
    </div>
  </div>
</template>
