[Feature request] Supporting multiple notices

[Mister-Hope]

Clear and concise description of the problem

Since users are allowed to set multiple notices, some page would possible hit multiple notice items.

Suggested solution

• We can allow displaying multiple non-fullscreen notice items when they are matched.

        [notice1]
        [notice2]

• Or we can detect notice matching state again once a notice item is closed, which means notice2 will be popped with animation once notice1 is closed.
