A user noticed that if they open the preview pane after logging in and then perform a search that the documents in the results pane will not load the preview which is already selected when the page loads.

I looked at the network traffic in the dev tool and do not see any errors aside from the getannotationpages section just not having a resolution time. it does have a server 200 response code  but looks like its still waiting on something.

To fix this you just click on one of the other tabs like fields or details and then back to preview and it loads fine. I've checked the web servers for errors but do not see anything in the event logs, but I may not know what i should be looking for as well. The error doesnt always occur too but it can be replicated pretty consistently every few tries.

Any thoughts or guidance would be appreciated
