Windowed Browsing not working

[Archimedes2110]

When the option "Open new windows in a tab instead" is unchecked/disabled, a Link with "target='_blank'" will still open in a new Tab instead of a new Window. Shift-Clicking the same Link will successfully open the desired new Window.

When the option is checked (so default), both ways will open a new Tab (like expected). So it seems to me like a Bug.
