Puzzle piece icon doesn't display tooltip

[ssokolow]

Some time within the last few days, my uMatrix gained a grayed-out puzzle piece toolbar icon. (It's currently at version 1.3.4 and, if it's relevant, I'm running Firefox Developer Edition 60.0b7 (64-bit) on a hybrid of Kubuntu and Lubuntu Linux 14.04 LTS.)

Since it was grayed out and I know that the WebExtensions API doesn't allow uMatrix to meddle with the innards of other browser addons (the intuitive meaning of that icon, given how Firefox uses it), I hovered my mouse over it to see the tooltip... no tooltip appeared.

I then tried hovering my mouse over the other icons and their tooltips appeared normally, so the event is getting delivered properly. I can only assume that you forgot to add a tooltip to it when implementing it. (Similar to how the vertical hamburger button is missing some kind of "additional options" tooltip to fall in line with the UI design recommendation that all icon-only UI elements should have clarifying tooltips.)

Whoops. Never mind. I somehow missed issue #975 on my first read-through of the open issues list.
