Annotations for child components within slots are lost

Debugging this a bit, the canvas-start/end markers are correctly rendered by the wrapping component, example:

<div id="nuxt-preview-humanifyheader" class="nuxt-preview-container" data-component-name="HumanifyHeader" data-component-props="{&quot;darkVariant&quot;:true,&quot;backgroundColor&quot;:&quot;crust&quot;}" data-component-slots="{&quot;branding&quot;:&quot;&lt;!-- canvas-start-aaef79ba-f04f-42bc-b888-e0229d46c9b5 --&gt;&lt;div id=\&quot;nuxt-preview-humanifylogo\&quot; class=\&quot;nuxt-preview-container\&quot; data-component-name=\&quot;HumanifyLogo\&quot; data-component-props=\&quot;{&amp;quot;linkToFrontPage&amp;quot;:true}\&quot; data-component-slots=\&quot;[]\&quot;&gt;&lt;\/div&gt;\n&lt;!-- canvas-end-aaef79ba-f04f-42bc-b888-e0229d46c9b5 --&gt;&quot;,&quot;navigation&quot;:&quot;&lt;!-- canvas-start-95805f3a-b32e-4d58-b08e-f506579ab18f --&gt;&lt;div id=\&quot;nuxt-preview-humanifynavigation\&quot; class=\&quot;nuxt-preview-container\&quot; data-component-name=\&quot;HumanifyNavigation\&quot; data-component-props=\&quot;[]\&quot; data-component-slots=\&quot;[]\&quot;&gt;&lt;\/div&gt;\n&lt;!-- canvas-end-95805f3a-b32e-4d58-b08e-f506579ab18f --&gt;&quot;}" data-once="nuxt-preview"><header class="dark bg-crust"><div class="min-w-sm mx-auto flex h-24 max-w-screen-xl items-center justify-between gap-x-12 px-4 sm:px-12 md:h-32 lg:gap-x-16 lg:px-16"><div class="h-12 flex-shrink-0 items-center justify-start md:h-16"><div style="display: contents;"><!-- canvas-start-aaef79ba-f04f-42bc-b888-e0229d46c9b5 --><div id="nuxt-preview-humanifylogo" class="nuxt-preview-container" data-component-name="HumanifyLogo" data-component-props="{&quot;linkToFrontPage&quot;:true}" data-component-slots="[]" data-once="nuxt-preview"><a class="inline-flex h-12 max-h-16 items-center gap-2 md:h-16" href="/"><span class="sr-only">Home</span><svg class="mt-2 h-full w-auto shrink-0" viewBox="0 0 489.142 489.142" xmlns="http://www.w3.org/2000/svg">...</svg><span class="text-flamingo shrink-0 text-lg uppercase tracking-widest"> Humanify </span></a></div>

so that part is working correctly

oh, I just figured that the canvas-start/stop comments are there but NOT the canvas-slot-start-UUID/SLOTNAME comments!

So we need to fix this first.

it turns out, this fixes the issue! So it seems the missing slot-comments were really the main problem

Merged!
