Is there a issue with shopify max modal?

Hi everyone,

We are experiencing the exact same issue starting today.

Our flow uses a ui-modal with variant="max" as the parent container. When we attempt to open a secondary modal (for example, a picker/preview dialog) from inside the max modal:

  • The child modal opens.

  • The parent max modal unexpectedly closes or becomes unmounted.

  • The overlay state becomes inconsistent.

  • We did not change any modal logic in our app.

This behavior was working correctly before today, which strongly suggests a recent platform change or regression in modal stacking behavior.

Could the Shopify team please confirm:

  1. Is nested modal behavior still officially supported?

  2. Has there been a recent change in ui-modal or max modal handling?

  3. Is there now a recommended pattern for opening secondary dialogs from within a max modal?

At the moment, this is blocking our production workflow since our UX depends on modal stacking.

Would appreciate clarification or confirmation if this is a known issue.

Thanks
