Timeseries: "Disconnect values" threshold incorrectly interpreted

### What happened? I have a disconnect value threshold of >1h set. But points that are only ~20m apart are left disconnected. In most but not all cases, it's every other pair of points. This timeseries plot has two different series. This issue is present for only one of the two. There are overrides applied to each series, but this property is not overridden.  ### What did you expect to happen? All points in this data set to be connected ### Did this work before? Usually this works, and it is working fine with the other series in the panel. ### How do we reproduce it? Use the attached debug panel. ### Is the bug inside a dashboard panel? Attached.
