Additional info

Upgrading from 28.0.1 to 28.0.2 RC1 also fails.

Browser console errors?

[rchaconmolero]

I have repeated the tests and it does work on relase 28.0.2 RC1. Not so in 28.0.1. We will wait for the final version of this version. There are no errors in the Chrome, Edge, or Firefox web console related to this issue. Thank you.

I have repeated the tests and it does work on relase 28.0.2 RC1. Not so in 28.0.1.

Then this is a duplicate of previously reported bugs and fixed in #42409.
