Fields populated by the iCloud password extension for Chrome are not considered filled by Chrome

I have the Chrome password manager extension, using my iCloud passwords.

It generally works fine with one significant and extremely annoying caveat.

When the autofill is triggered and the fields are populated, if the submit is immediately pressed, the respective website says that the fields are empty. Usually in the form of validation warning (that the username an password are required fields for the respective form) - see the attached screenshot.

Depending on the stylesheet of the respective site one can actually see that the input text from this autofill operation is treated differently than if the text was manually typed, as it usually appears in a more pale tone.

The workaround is to manually add and delete a symbol in both fields, so to trick Chrome into thinking there is something written in the fields. And that is SOOOOOOOOO annoying.

Does anyone else experience that? That happens on different Windows machines (on Chrome).
