Select widget isn't visible

Hi Dieter,

Could you provide more info, please?

I was not able to reproduce the reported issue.

Testing steps

Using a clean installation of latest version of Drupal (Claro by default) and Tagify:
1. Add a new entity reference field (Using taxonomy terms) and set Tagify Select as widget.
2. Create and Article, and the entity reference field using Tagify Select widget is working as expected.

Could you check if something that you have added to the project is interfering with the tags?

I tried to turn off a bunch of custom and contrib code, but no change. I can see the hidden class is added in Drupal\tagify\Element\SelectTagify::preRenderSelect(), but where exactly is it removed?

I'm using the latest version of Drupal core and the Tagify module. I tried switching from Gin to Claro, but that doesn't fix it. This is the JS library version that's being loaded: https://cdnjs.cloudflare.com/ajax/libs/tagify/4.26.0/tagify.min.js

After a lot of trial and error I have been able to track down the issue. The Anti Duplicates module → defines the following style:

.hidden {
  display: none !important;
}

This hides the Tagify widget. The class isn't even being used in the module, so I'll remove it there.
