Active tab not marked in menu

[stefankapp]

Hi,
I found that the menu item of the active tab is not highlighted on my dashboard.
In an earlier version of the dashboard, the highlighting was working fine (don't know which exactely it was).

I uninstalled Node-RED, Node.js and deleted the .node-red and npm-cache folders and the browser cache.
I reinstalled Node.js , Node-RED and node-red-dashboard and created a new flow with two tabs. In the menu of the dashboard, the active tab item is still not highlighted. On the attached picture, "Board 2" should be highlighted. If "Click to show side menu" is selected, the issue is the same.

Do you have any idea why this could occur or how it can be avoided?

Thank you and best regards
Stefan
