Executed Tests

Manual tests on my local instance (see video above).
Built the changes with mvn clean install -f xwiki-platform-core/xwiki-platform-notifications/xwiki-platform-notifications-ui -Pquality succesfully.
I checked the test objects and it seems like the affected object is the WatchButton:

xwiki-platform/xwiki-platform-core/xwiki-platform-notifications/xwiki-platform-notifications-test/xwiki-platform-notifications-test-pageobjects/src/main/java/org/xwiki/platform/notifications/test/po/NotificationWatchButtonElement.java

Lines 35 to 36 in 5f90563

	@FindBy(id = "watchButton")
	private WebElement watchButton;

This is used in a few tests, NotificationsSettingsIT#filterAndWatchedPage is one of them so I decided to check that docker tests were okay with mvn clean install -f xwiki-platform-core/xwiki-platform-notifications/xwiki-platform-notifications-test/xwiki-platform-notifications-test-docker/. The docker tests passed successfully after a few minutes running on my machine.
