Fieldsets with only images don't display

Seems like something that could be a configuration in the form

Yup, after the upgrade to 4.0, all image-only fieldsets don't show. Patch works great. Lets push!

I have a slightly different issue.
$child->content is not a string, in my case, but a Drupal\Core\Render\Markup.
Any advice? :(

Thank you

Think this should be a configuration form so you can choose tags, that may solve it.

Sorry @smustgrave,

I've updated my comment, It is a different issue.
Please see above.

Thank you.

Here is a snapshot.

Found the culprit,

the ['#markup' => "html goes here'] had to be wrapped in render() function.

I'm using module v 4.0.0 with Drupal 10.1.6. Have a fieldset (div wrapper) with only image field - image not rendered.
Patch solved the issue.

I'm moving to RTBC.

Since there could be other tags, thing this should be a configuration form to allow others tags if needed.

I'm using the module Views Entity Form Fields → to display form fields in a view. Any form fields in a fieldset (on their own) don't display (same behavior as img).

@smustgrave is right, there needs to be support for more tags.

This bug is connected to: #3369756 Empty fields are not hidden ✨ Empty fields are not hidden Fixed

@smustgrave
I don't think adding a configuration is the right way. It's about checking whether the rendered output of the fieldset is empty or not. We should fix/refactor code changes committed in #3369756

Holy cow - I spent the day trying to figure out why my images weren't displaying; I'm rebuilding from a dev site and in creating the identical view, one view displayed images while the other didn't. I was going nuts. Then I found this post. Patch fixed it and, sure enough, I see that the dev site was running 8.34.

I think this should be more heavily flagged, though, if possible - those doing upgrades on live sites could easily have all their images disappear without having a clue as to what did it. Just sayin'.

Thanks for the module... and for the fix... Whew!

Another quick workaround add hidden span tag <span class="hidden">&nbsp;</span>.

The patch didn't work for version 4.0.1 so I created a patch for that version. I can confirm now the images do work again.
