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.

Commencez par reproduire le comportement du double-clic sur le trackpad d’un ordinateur portable par rapport à une souris pour la restauration du zoom et les interactions avec la légende. Comparez les deux périphériques d’entrée dans les interactions concernées du graphique et déterminez ce qui doit changer pour que tous deux reconnaissent les doubles clics ; le travail est terminé lorsque les deux gestes signalés fonctionnent sans perturber le comportement de la souris.
