[BUG] Bookmark isn't available when navigating many reports

Hi,

I think I found a bug in Power BI Service. I have several Power BI Premium workspaces and sometimes a wrong bookmark ID is generated and it causes an error. Here is an example of the actions I did:

1. Open Workspace 1 (Premium) and open Report 1
2. Navigate the report by using some links used in the buttons of the report. Let's say that the navigation experience ends with bookmark ID Bookmarkabcdefg12345.
3. Open Workspace 2 (Premium)
4. By mouseover on the link of Report 2, I see that the last argument of the URL is bookmarkGuid=Bookmarkabcdefg12345 (it's the same ID used in Report 1). Clearly, if I open this link, the error "The bookmark isn't available" comes up becasuse the bookmark doesn't exist in Report 2 (instead, it does in Report 1).

Thanks!
