CKEditor tests are failing with selenium/standalone-firefox:107.0

Selenium has recently released a new version of the docker image for using Firefox which is selenium/standalone-firefox:107.0 also released with tag latest. And by default we do use the latest tag to our docker tests. However there's apparently an issue when executing the CKEditor tests with that version of the browser: for some reasons the keyboard keys are never sent to the editor.

The video related to CKEditor.SaveIT#saveAfterSyntaxChange seems to show that the editor is reloaded after the Keys.HOME is sent to the editor. I suspect that the problem might be related to switching to the iframe or selecting the active element in the browser.
