Middle click to close tab triggers paste on Linux

[aruhier]

Hi,
On Linux, doing a middle-click on a tab in Sidewise, to close it, will trigger a paste in the search bar if the bar was focused. I don't know if it's a bug from Sidewise or Chrome, but the middle-click should be catched and not given to the search bar in this case, as it's a way to "xpaste" on Xorg.

Tell me if you want more details or examples about that.

Thanks!
