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.

まず、ズームの復元と凡例の操作について、ノートパソコンのトラックパッドとマウスでのダブルクリックの挙動を再現します。影響を受けるグラフ操作で2つの入力デバイスを比較し、両方でダブルクリックを認識できるようにするには何を変更する必要があるかを判断します。完了の条件は、マウスの挙動を壊さずに、報告された両方のジェスチャーが機能することです。
