Keyboard shortcut regression since S&T integration

[anevilyak]

In revisions following the integration of stack and tile, opt+cmd menu shortcuts no longer work (examples include the ones used for instance to invoke Tracker add-ons).

This is much broader than what's described in #7112 though, and I wasn't even referring to that navigation shortcut anyways, but things like file types and backgrounds (opt+cmd+f/opt+cmd+b). This is universally eating any opt+cmd shortcut in any app, regardless of whether Stack and Tile makes use of it or not, and now that it's integrated, one can no longer opt out of it by not using S&T. I'm sorry, but this needs to be fixed.
