SLA Widget instance limit in UIv4 Dashboards - no error message when exceeded

The SLA widget (unfortunately) has a 2000-instance limit. In UIv3, when the limit is exceeded the widget will show an error message saying “instance limit of 2000 is exceeded”. So this at least tells me what the issue is.

In UIv4, when the instance limit is exceeded for an SLA widget it just says “NaN” with no specific error message. It should at least show the same error message as before so users know why the widget is not populating.
