keyboard layout English US, intl, with dead keys not working

I usually use two keyboard layout, plain `English (US)`, and `Englis (US, intl. with dead keys)` in order to type `'` and press `e`, to make this: `é`.

It worked in many distributions (including Ubuntu and Ubuntu derivatives) for many years, now on a fresh installation of Ubuntu 18.04.5 LTS I have problems. The layout `US Intl. with dead keys` work as the plain US layout: I can not type `é`.

Even the `Englis (US, intl. with AltGr dead keys)` does not work properly. I obtain `é` by pressing `AltGr+e`, but if I press `AltGr+'` followed by `e` I obtain `'e`. This means that the switching of keyboard layouts is working properly.

Note that `Englis (UK, intl. with dead keys)` works properly, the problem is specifically related to `Englis (US, intl. with dead keys)`

The bug seems not to be related to hardware since I tested with different USB wired keyboards.

Does it happen with a different keyboard too?

I was seeing this issue ("US, intl., with dead keys" keyboard layout dead keys not working) after upgrading from Ubuntu Budgie 21.04 to 21.10 but it resolved itself after I removed my "US, intl., with dead keys" input source and added it back again.
