Steps to reproduce

Angular application in production mode

JS code that you use to initialize lightGallery.

protected lgSettings: LightGallerySettings = {
    selector: ".thumbnail",
    plugins: [lgZoom, lgThumbnail],
    licenseKey: LIGHT_GALLERY_KEY,
};

Sample HTML markup

<lightgallery class="light-gallery" [settings]="lgSettings" [onInit]="onLgInit">
    @for (img of allScreenshots; track img) {
      <div class="thumbnail" [attr.data-src]="img.image">
        <img [src]="img.thumbnail" />
        @if (img.type === "custom") {
          <button mat-mini-fab class="delete-button" color="warn" (click)="onDeleteScreenshot(img, $event)">
            <mat-icon>delete</mat-icon>
          </button>
        }
      </div>
    }
  </lightgallery>

Environment

• Browser and version - Firefox Developer Edition, v125.0b6
• OS - Windows
• lightGallery version - 2.7.2

Additional context

This is working fine in Chrome, I haven't tried with the classic edition of Firefox.
The error appears once I click on a picture.
I have tried to set gfx.downloadable_fonts.sanitize to false in about:config but it didn't work (I'd rather keep it activated anyway).

Here is how I import scss:

styles.scss

@import "./styles/lightgallery";

lightgallery.scss

@import "lightgallery/scss/lightgallery";
@import "lightgallery/scss/lg-thumbnail";
@import "lightgallery/scss/lg-zoom";
