Refresh herosizing calculations

I have a single page app that lets the user flip between a discussion and tasks.
The discussion pages uses herosizing plugin to pin the comment input to the bottom and works fine until the user switches from a task back to the discussion and then I lose my comment input presumably because the page height has changed or something on the task. If I refresh/load the page it’s fine, so wondering how I can reset the elements that would be impacting the herosizing without refreshing the page
