Wrong item content in the browser

On the beta-view: I first thought this just the search feature, but clearing the filter to see on unfiltered results, if I click through saved items, not all of them update on the right hand detail view.
It randomly holds focus. It doesn't seem to be latency, as once an entry that doesn't update, multiple clicks on it doesn't trigger the update either. It did seem like it was the same entries that repeatedly didn't want to update.

I didn't close my browser, but I switched back to the original view, and then back to the beta view and then the locked focus/no-update-on-selection problem disappeared.

Maybe the first load of the webpage doesn't initialize everything correctly, but it seems to self-rectify, as I haven't been able to recreate the behaviour since.
