Claro toolbar.theme.css aggregation issue

Changes are made on on 11.x (our main development branch) first, and are then back ported as needed according to the Core change policies → . And restoring issue, which is used to track progress and various tasks on an issue.

Is that the only file with this problem on the affected site?

I am adding the "Needs steps to reproduce" tag because having installed a new Drupal 11 site to test this, I don't see the problem. What other factors could be involved?

I don't either understand. I don't know why, even after deleting web/core and reinstalling, my site has this :

 /**
  * Toolbar bar.
  */
 .toolbar .toolbar-bar {
   color: #ddd;
   background-color: #0f0f0f;
-  box-shadow: -1px 0 3px 1px rgba(0, 0, 0, 0.3333); /* LTR */
+  box-shadow: -1px 0 3px 1px rgba(0, 0, 0, 0.3333);
+  /* LTR */
 }

When the comment /* LTR */ is on the same line as box-shadow, the issue happens.

Oh sorry, it was my fault, I was applying this patch ( https://www.drupal.org/files/issues/2024-06-13/3198565-23.patch → ), from https://www.drupal.org/node/3198565 → , and it was causing this error.

Thank you for your time.
