img-grid occasionally fails to find file -- seems like being resolved by wrong page

[pleasantone]

Scenario:

I use {{< bs/img-grid "attendees.yaml" >}} to build an image grid of photos of people attending an event on a page.
The images are stored in the page bundle, in a subdirectory e.g. attendess/foo.jpg.

Anomaly:
Page always builds correctly in production.
Sometimes, in development, e.g. if one edited that page bundle's index.md, the images are not found.
If one triggers a rebuild, they will often be found.
github.com/hugomods/images/layouts/partials/images/image.html reports that the images that were part of the page resources was not found.

Analysis:
By adding some debugging, I've determined that when things have failed, it has occurred because image.html's $page variable is Page(/_index.md) not Page(/events/2024-baja-mexico/index.md) (the proper page).

Strongly enough, the call to github.com/hugomods/bootstrap/layouts/partials/bootstrap/img-grid.html (one level up in the call stack) is always called with the proper Page set.

Here's my debugging output when it fails:

Here is my debugging when it succeeded:

My best guess is that something is partialCached when it shouldn't be, but this is really weird.. the page in question is just using a standard shortcut...

My debugging diffs:
bootstrap.patch
images.patch

Update:

Happens when .Page for this short-cut is nil. Looks like we cover it with

$page = default page .Page in image.html why is .Page nil when it was just fine when being called one step up by the bootstrap bs/img shortcut pulling in the data file?
