when ssrMode is set to true, client side pollInterval is not enabled

[karmingc]

Background
Currently working with Next.JS and hoping to use pollInterval on the client side. Unfortunately, this seems to be disabled when we turn ssrMode: true. Would love to know how to approach this.

Intended outcome:
polling is enabled when user visits the page.

Actual outcome:
polling is not enabled.

How to reproduce the issue:
set ssrMode: true and use pollInterval in a component
