Steps to reproduce:

Host dashboard auto refresh the browser page every minute.
In case of widget with multiple item : 

It lose the selected one on refresh. For exemple, load the host dashboard, select item 2, wait 1 minutes, the page is reloaded and you'r back on item 1.

This is not related to graph refresh, it's disabled in my widget, and there is only one widget on the page : 

On the browser network, i see this : 

notifications.get and jsrpc.php are reccurent and does not seems to do anything in this issue. 

But when the call dashboard.config.hash happen, I instantly get a refresh on host.dashboard.view. 

I find this is annoying, as you have 1 minute to get the information you wan't, before you come back to default dashboard. 

I couldn't find similar bug reported, only found this forum post without news or bug report reference : https://www.zabbix.com/forum/zabbix-help/507125-zabbix-7-0-17-keeps-refreshing-dashboard-and-loosing-selected-item-in-navigator
