The interaction with links in the Echo flyout is somewhat erratic, presumably due to the interaction between JavaScript-fired events and the regular links.
Most notably, loading a link in a background tab doesn't always work consistently. In Chrome/Ubuntu, opening any link via middle-click loads it in a background tab as well as in the current foreground tab. This does not happen when using right-click. Ignatzmice is reporting the same behavior when CMD-clicking on a Mac:
Version: unspecified
Severity: normal
