NewsBlur: Web: 'v'/'o' no longer open stories in background

Chrome 41.0.2272.16 beta (64-bit) OS X Mavericks 10.9.5

Preference Stories > Open Links > In New Tab is selected. Using ‘Feed’ view and ‘Full’ mode (not ‘List’).

Focusing a story via ‘j’/‘k’ and then pressing ‘o’ opens the story in a foreground tab. The expected behavior is for it to open in a background tab.

I’m assuming Chrome just updated because it was definitely working last weekend and other than possibly Newsblur that’s the only thing that could be different.

I’m not seeing any errors or warnings in the Console, so I’m guessing Google changed the handling of MouseEvents. In looking at the open_story_in_new_tab function within NewsBlur/media/js/newsblur/models/stories.js I notice it uses init_mouse_events which MDN says is deprecated. I’m not well versed in JS and my attempt at changing that (and the previous line) to b = new MouseEvent("click", {bubbles: true, cancelable: true, view: window, ctrl:true, meta:true}); in Chrome’s dev tools only made it open the link in the current tab instead.
