If I understand you correctly, you cannot define “which inner” shortcode you want to address. .Inner
is always the whole content. In this case both inner shortcodes.
I had a similar problem and solved it like this. Put something like this in the shortcode that comes first (I assume the order will not change, so in your case jumbo_intro), this should be the very last thing of the file:
--break-me-here--
Then in your jumbo shortcode, you break the .Inner
content into an array and pull the right thing in the right place:
{{- $children := split .Inner "--break-me-here--" -}}
<div class="jumbotron jumbotron-fluid">
<div class="container">
<div class="row">
<div class="col-6">
{{- index $children 0 | safeHTML -}}
</div>
<div class="col-5 offset-1">
{{- index $children 1 | safeHTML -}}
</div>
</div>
</div>
</div>
