Description

Moving tabs lags significantly when the "Packages" submenu of the settings view pane has been loaded.

Steps to Reproduce

Not replicable in safe-mode. Disabled all packages except for settings-view and tabs and did this:

Expected behavior: Tab movement to remain quick and responsive.

Actual behavior: Tab movement very laggy.

Reproduces how often: 100% of the time when "Packages" sub-menu has been loaded (doesn't have to be in focus). 0% of the time otherwise.

@50Wliu Do you think atom/tabs#390 would fix this?

It's possible.
