Double clicks not recognized through the trackpad

I've seen a number of issues/bug reports concerning double click behavior, both here on GitHub and on Stack Overflow.

For my part, I noticed that none of the double click gestures were being picked up--in particular, double click to restore zoom level, or double click on legend to hide all other traces.

I observed this behavior while using my laptop's trackpad. However, when I plugged in a mouse, double clicks using that device were recognized just fine. I don't have trouble double clicking using the trackpad in other applications.

I know this issue report is kind of general, and doesn't really zero in on where the problem lies, but I thought I'd throw in this bit of information in case it helps in diagnosing.

Beginne damit, das Doppelklickverhalten auf einem Laptop-Trackpad im Vergleich zu einer Maus für die Wiederherstellung des Zooms und die Interaktionen mit der Legende zu reproduzieren. Vergleiche die beiden Eingabegeräte bei den betroffenen Diagramminteraktionen und ermittle, was sich ändern muss, damit beide Doppelklicks erkennen; abgeschlossen ist die Aufgabe, wenn beide gemeldeten Gesten funktionieren, ohne das Mausverhalten zu beeinträchtigen.
