Pinned live page dashboard blank when token refreshes in javascript api

Hi, one of my clients embedded a Power BI dashboard into a webpage using javascript.

They were using the powerBI javascript client , doing something quite similar to this example.

As the Power BI authentication expires every hour or so, they had to request for a new token on a regular basis.

When the dashboard includes a pinned Live Page, when the token is refreshed, the visualization goes blank.

However, when a dashboard includes pinned tiles, the visualization remains there when the token is refreshed.

Anyone knows why and how to fix this?

Thanks.
