Analysing a temperature item gives a graph where the popup does not follow date time formatting


I have multiple temperature and humidity items for which I can use “Analyze” to see a nice graph showing variations in time.
With this, I can place my mouse cursor on top of a given data point and see a popup giving me nice details.
However, I noticed that the date/time shown in there is always using the AM/PM format where I have setup the rest of the interface to use the 24h format.
Here is a screen capture showing the issue:

If you look at the x axis, you see it is using the appropriate date/time format, while the popup at the top is not.
Note that this only occurs with Analyze, if I create a graph page, the popup there is using the same format as the x axis.

What setting have I missed?
