Miscalculation of template cache potential #8125
Description
As report by @davidsneighbour at https://discourse.gohugo.io/t/30475/3.
A HTML-only partial shows a cache potential of 0 instead of 100.
For example:
<div class="progress" id="readingprogress">
<div class="progress-bar"
id="readingprogress-bg"
role="progressbar"
aria-label="Readingprogress"
aria-valuenow="0"
aria-valuemin="0"
aria-valuemax="100"></div>
</div>
